Netbeans and Multiple jFrames

Question

Hey,
Does anyone know how to make an application have multiple windows/jFrames with Netbeans 5.5's GUI builder?
I created another jFrame in my application by right-clicking on my source package in the Projects window and selecting New... --> jFrame Form...
How do you make the new jFrame form I created become visible from the first jFrame form I have?
Once I have that new form visible, how do I make it do stuff to the first jFrame form?

Here's a little example:
import javax.swing.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
class Frame1 extends JFrame {
     private JButton button;
     public Frame1() {
          initComponents();
     private void initComponents() {
          button = new JButton("New Frame");
          button.setSize(100, 20);
          button.setLocation(5, 5);
          this.getContentPane().setLayout(null);
          this.getContentPane().add(button);
          this.pack();
          this.setSize(400, 400);
          this.setLocationRelativeTo(null);
          this.setDefaultCloseOperation(EXIT_ON_CLOSE);
          this.setTitle("Demo");
          button.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent evt) {
                    new Frame2().setVisible(true);
     public static void main(String[] argv) {
          new Frame1().setVisible(true);
class Frame2 extends JFrame {
     private JMenuBar jmb;
     private JMenu menu;
     private JMenuItem exitItem;
     public Frame2() {
          initComponents();
     private void initComponents() {
          jmb = new JMenuBar();
          menu = new JMenu("File");
          menu.setMnemonic((int)'F');
          exitItem = new JMenuItem("Exit");
          exitItem.setMnemonic((int)'X');
          jmb.add(menu);
          menu.add(exitItem);
          this.setJMenuBar(jmb);
          this.pack();
          this.setSize(100, 100);
          this.setTitle("Demo 2");
          this.setDefaultCloseOperation(EXIT_ON_CLOSE);
          this.setResizable(false);
          this.setLocationRelativeTo(null);
          exitItem.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent evt) {
                    System.exit(0);
}
