Generating layout with xml

Question

Hi,
I want to make a graphical user interface with xml.
Is that possible?
For example:
<?xml version="1.0" encoding="UTF-8" ?>
<JMenubar>
<JMenu name="Program">
<JMenuItem name="Connect" method="Connect()" />
</JMenu>
</JMenubar>
I automatically want to create these menu.
But this xml could be more extended, and then the layout must also made automatically.
The problem is, that you don't know how many JMenu's en JMenuItems there are.
Anyone has an idea how to work with this?

One way to do this is just to use XMLEncode & XMLDecode, so a nice example for you, to run this, first
java Test -c test.xml
It will ask some questions, fill 'em in.
then
java Test -l test.xml
and it'll create a frame based on the XML file created by step one.
import java.beans.*;
import javax.swing.*;
import java.io.*;
class Test {
    public static void main(String argv[] ) throws Throwable{
     String file = "default.xml";
     JFrame frame;
     if( argv.length > 1 && argv[1] != null ) {
         file = argv[1];
     if( argv[0] != null && argv[0].equals( "-l" ) ) {
                XMLDecoder d = new XMLDecoder
                 ( new BufferedInputStream
                ( new FileInputStream( file ) ) );
             frame = ( JFrame ) d.readObject();
             frame.pack();
             frame.show();
             return;
     if( argv[0] != null && argv[0].equals( "-c" ) ) {
         System.out.println( "Frames Title:" );
         BufferedReader in = new BufferedReader
            ( new InputStreamReader ( System.in ) );
         String title = in.readLine();
         frame = new JFrame( title );
         frame.setDefaultCloseOperation( frame.EXIT_ON_CLOSE );
         System.out.println( "utton or [L]abel" );     
     String bOrl = in.readLine();
     System.out.println( "Objects Title: " );     
     title = in.readLine();
     bOrl = bOrl.toUpperCase();
     JComponent obj;
     if( bOrl.startsWith( "B" ) ) {
          obj = new JButton( title );
     } else {
          obj = new JLabel( title );
     frame.getContentPane().add( obj );
     System.out.println( "Number Of Menus" );
     String noS = in.readLine();
     int no = Integer.parseInt( noS );
     JMenuBar bobTheMenu = new JMenuBar();
     JMenu menu = new JMenu( "File" );
     bobTheMenu.add( menu );
     frame.setJMenuBar( bobTheMenu );
     for(int counter = 0; counter < no; counter++ ) {
          System.out.println( "MenuItem " + counter + " title: " );
          title = in.readLine();
          menu.add( new JMenuItem( title ) );
     System.out.println( "Saving" );
     XMLEncoder e = new XMLEncoder
     ( new BufferedOutputStream
     ( new FileOutputStream( file )));
     e.writeObject( frame );
     e.close();
