Little help with a NameChangeListener and Event

Question

Hi,
This is very simple but having some trouble. Ive written my NameChangeEvent class and NameChangeListener. I also have a 'MainWindow' class which is a frame and on that frame I have a text field and a button. The button is called 'change name' and when I press this a JOptionPane comes up saying 'Please enter new name'. Now this is where i'm stuck....I want the new name to appear in the text field in the MainWindow but can't remember how to do this??
Thanks alot.

Yeh i've done all that, here is my classes.
package explicit;
import java.util.EventListener;
public interface NameChangeListener extends EventListener {
     public void nameChanged(NameChangeEvent event);
package explicit;
import java.util.EventObject;
public class NameChangeEvent extends EventObject {
     private String name;
     public NameChangeEvent(Object source, String name) {
          super(source);
          this.name = name;
     public String getName() {
          return name;
}But i'm stuck here....
     private JButton getChangeNameButton() {
          if (changeNameButton == null) {
               changeNameButton = new JButton();
               changeNameButton.setBounds(new Rectangle(60, 58, 127, 23));
               changeNameButton.setText("Change Name");
               changeNameButton.addActionListener(new java.awt.event.ActionListener() {
                    public void actionPerformed(java.awt.event.ActionEvent e) {
                         JOptionPane.showInputDialog(MainWindow.this, null, "Please enter in name",1);
          return changeNameButton;
     }What do i code in here?
