not sure what you are doing but, if you you do a standard little program ..

import java.awt.*;
import javax.swing.*;

public class test extends JFrame
{
public static void main(String args[])
{
this.setSize(100,100);
this.setLocationRelativeTo(null);
this.setVisible(true);
}
}

you SHOULD be getting a JFrame (window) in the center of your screen, of size 100 by 100 pixel (Plus decorations ... ie the frame itself).

I didn't test that but it should compile and run (though i could be wrong) if you save it as test.java

Of course it's only a start and you need to add buttons and all the other fun things ...

IF you want a definitely working example of how to do it ... check out my website (bottom link in my signature - naiv.sourceforge.net) and grab the latest pre release, which generates a tabbed pane with multiple options via checkboxes, comboboxes, spinners, as well as having a JMenu on it's main window and a popupmenu

(to see the options screen click Edit>Preferences)

Good luck (else might be worthwhile to post your code, and the errors ...)

OH one other thing, if you are adding to a frame, make sure you don't frame.add() rather do frame.getContentPane().add()

good luck
