JDialog size and components visibility

Question

hi
I have a JDialog in which i have a panel and in the panel i have the components arranged as
Label1 Label2
Label3 TextBox1
Label4 TextBox2
Button1 Button2
I have used GridBagLayout for the panel as well as for the Dialog.The following is the code i have used to create the JDialog,panel and its components
JDialog inputdialog=new JDialog(this,true);
inputdialog.setTitle("Modify");
GridBagLayout layout=new GridBagLayout();
JPanel panel=new JPanel();
panel.setLayout(layout);
GridBagConstraints gbc = new GridBagConstraints();
JLabel key=new JLabel("Key");
gbc.gridx=0;
gbc.gridy=0;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.anchor=gbc.CENTER;
layout.setConstraints(key,gbc);
panel.add(key);
JLabel keylabel=new JLabel();
keylabel.setText("SIMPLE");
gbc.gridx=1;
gbc.gridy=0;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.anchor=gbc.NORTHWEST;
// gbc.insets=new Insets(0,0,0,200);
layout.setConstraints(keylabel,gbc);
panel.add(keylabel);
JLabel value=new JLabel("Value");
gbc.gridx=0;
gbc.gridy=1;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.anchor=gbc.CENTER;
layout.setConstraints(value,gbc);
panel.add(value);
JTextField valueTextField=new JTextField();
gbc.gridx=1;
gbc.gridy=1;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.anchor=gbc.NORTHWEST;
gbc.ipadx=100;
layout.setConstraints(valueTextField,gbc);
panel.add(valueTextField);
JLabel comment=new JLabel("Comment");
gbc.gridx=0;
gbc.gridy=2;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.anchor=gbc.CENTER;
gbc.insets=new Insets(0,125,0,3);
layout.setConstraints(comment,gbc);
panel.add(comment);
JTextField commentTextField=new JTextField();
gbc.gridx=1;
gbc.gridy=2;
gbc.gridwidth=3;
gbc.gridheight=1;
gbc.ipadx=300;
gbc.insets=new Insets(0,0,0,70);
gbc.anchor=gbc.NORTHWEST;
layout.setConstraints(commentTextField,gbc);
panel.add(commentTextField);
JButton ok=new JButton("OK");
gbc.gridx=1;
gbc.gridy=3;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.ipadx=30;
gbc.ipady=10;
layout.setConstraints(ok,gbc);
panel.add(ok);
JButton cancel=new JButton("Cancel");
gbc.gridx=2;
gbc.gridy=3;
gbc.gridwidth=1;
gbc.gridheight=1;
gbc.ipadx=30;
gbc.ipady=10;
gbc.insets=new Insets(0,0, 0,150 );
layout.setConstraints(cancel, gbc);
panel.add(cancel);
inputdialog.setLayout(layout);
gbc.gridx=0;
gbc.gridy=0;
gbc.ipadx=0;
gbc.ipady=0;
gbc.anchor=gbc.FIRST_LINE_START;
gbc.insets=new Insets(80,0,900,1000);
layout.setConstraints(panel,gbc);
inputdialog.getContentPane().add(panel);
inputdialog.setSize(400,200);
inputdialog.setVisible(true);
My question is i have set the Dialog size using setSize(400,200) but when the dialog is opened the components are not visible for that size of the dialog,the components appear only when the Dialog is maximized,i do not want that to happen i want the components to appear in the Dialog when the size of the Dialog is (400,200) and not when it is maximized.What should i do?
thanks

Hopefully this example would give you some ideas:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class DialogTest extends JFrame implements ActionListener {
     public DialogTest() {
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JButton button = new JButton("Show Dialog");
          button.addActionListener(this);
          getContentPane().add(button);
          pack();
          setLocationRelativeTo(null);
          setVisible(true);
     public void actionPerformed(ActionEvent e) {
          JDialog dialog = new JDialog(this, true);
          dialog.setTitle("Testing");
          JPanel panel = new JPanel(new GridBagLayout());
          GridBagConstraints c = new GridBagConstraints();
          JLabel label;
          JButton button;
          JTextField textField;
          label = new JLabel("Key");
          c.gridx = 0;
          c.gridy = 0;
          c.insets = new Insets(5, 10, 5, 10);
          c.anchor = GridBagConstraints.CENTER;
          c.fill = GridBagConstraints.HORIZONTAL;
          panel.add(label, c);
          label = new JLabel("SIMPLE");
          c.gridx = 1;
          c.gridy = 0;
          panel.add(label, c);
          label = new JLabel("Value");
          c.gridx = 0;
          c.gridy = 1;
          panel.add(label, c);
          label = new JLabel("Comments");
          c.gridx = 0;
          c.gridy = 2;
          panel.add(label, c);
          textField = new JTextField(10);
          c.gridx = 1;
          c.gridy = 1;
          c.gridwidth = 2;
          c.insets = new Insets(5, 10, 5, 120);
          panel.add(textField, c);
          textField = new JTextField(20);
          c.gridx = 1;
          c.gridy = 2;
          c.insets = new Insets(5, 10, 5, 10);
          panel.add(textField, c);
          button = new JButton("OK");
          c.gridx = 1;
          c.gridy = 3;
          c.ipadx = 50;
          c.gridwidth = 1;
          panel.add(button, c);
          button = new JButton("Cancel");
          c.gridx = 2;
          c.gridy = 3;
          c.insets = new Insets(5, 5, 5, 50);
          panel.add(button, c);
          dialog.getContentPane().add(panel);
          dialog.pack();
          dialog.setVisible(true);
     public static void main(String[] args) { new DialogTest(); }
}
