Resize frame

Question

I use NetBeans 5.5
With help of GUI Builder I made a JFrame Form.
Then, I add a class which extends JPanel to my Form.
This Class has Panel with JTable and a panel with some buttons.
The problem is:
Frame doesn't resize after my class adding.
User sees half om my JTable. So he has to resize frame window manually.
Is there any way to get "real" size of my frame (including added components) and resize frame to "real" size?

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class FrameProblem extends JPanel{
    /** Creates a new instance of FrameProblem */
    public FrameProblem() {
        JTabbedPane tabbedPane = new JTabbedPane();
        JPanel baseBanel = new JPanel();
        JPanel buttonPanel = new JPanel();
        JButton button = new JButton("Control button");
            buttonPanel.add(button);
        DefaultTableModel dtm = new DefaultTableModel();
            dtm.setColumnCount(5);
            dtm.setRowCount(30);
        JTable table = new JTable(dtm);
            this.add(table);
            this.add(buttonPanel);
        //this.add()
    public static void main(String[] args){
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                JFrame frame = new JFrame();
                frame.setSize(30,30);
                JTabbedPane tabbedPane = new JTabbedPane();
                tabbedPane.add("my class with JTable", new FrameProblem());
                frame.add(tabbedPane);
                frame.setVisible(true);
                frame.pack();
As you can see, everything is OK!
frame resizes to FrameProblem class dimension.
As i have wrote before, I think problem is in the interaction between GUI Builder designed components and manually wrote components
