Appearance of a Dialog

Question

Hi here is my code
public class AudibleHelpDialog extends JDialog{
public ResourceBundle strings = ResourceBundle.getBundle("DefaultSound");
public String HELP = strings.getString("Help");
public static final String DIALOG_TITLE = "Audible Alert Help";
UIJPanel mainPanel = new UIJPanel();
JTextArea text = new JTextArea();
JButton ok = new JButton();
AudibleHelpDialog(JFrame parentFrame,String str,boolean modal)
super(parentFrame,DIALOG_TITLE,true);
init();
public void init()
setResizable(false);
mainPanel.setLayout(new BorderLayout());
text.setText(HELP);
text.setVisible(true);
text.setSize(20,30);
text.setEnabled(false);
text.setBackground(Color.DARK_GRAY);
text.setLineWrap(true);
ok.setText("OK");
ok.setSize(20,30);
//ok.setPreferredSize(new Dimension(70, UIConstants.UI_BUTTON_HEIGHT));
ok.setMaximumSize(new Dimension(70, UIConstants.UI_BUTTON_HEIGHT));
ok.setMinimumSize(new Dimension(70, UIConstants.UI_BUTTON_HEIGHT));
ok.setPreferredSize(new Dimension(70, UIConstants.UI_BUTTON_HEIGHT));
text.setMaximumSize(new Dimension(200, UIConstants.UI_FIELD_HEIGHT));
text.setMinimumSize(new Dimension(200, UIConstants.UI_FIELD_HEIGHT));
text.setPreferredSize(new Dimension(200, UIConstants.UI_FIELD_HEIGHT));
ok.addActionListener(new java.awt.event.ActionListener()
public void actionPerformed(ActionEvent e)
buttonOk_actionPerformed(e);
mainPanel.add(text,BorderLayout.CENTER);
mainPanel.add(ok,BorderLayout.SOUTH);
this.setContentPane(mainPanel);
//setModal(true);
setTitle(DIALOG_TITLE);
setLocation(200,200);
setSize(250,200);
setVisible(true);
//getContentPane().add(mainPanel);
// getContentPane().add(mainPanel);
}On setting the size of my textarea and button, it is not taking the size specified, but occupies whole window.I am not knowing how to proceed..
