Get data from Dialog Window.

Hello, I have a problem with a Dialog Window, it has a TextField and a Button in order to input a String. Till here, everything works fine, but the problem is How to send this String value to parent window ?.
Here's the code:

 import java.awt.*;


public class window3 extends java.applet.Applet {
 Frame marco;
 Button abre;
 TextArea ta;

 
   
 public void init() {
  resize(140, 100);
  ta = new TextArea(3,10);
  abre = new Button("Open window");
  ta.appendText(nuevoNom);
  add(ta);
  add(abre);
  marco = new MiMarco("Change Name Window");
  marco.resize(380,50);
  marco.hide();
 }

 public boolean action(Event evt, Object algo) {
  Object target = evt.target;
 
  if(target == abre) {
    marco.show();
   return true;
  }

  return false;
 }
 
}
 



 
 class MiMarco extends Frame {
  String nuevoNom;
  TextField newnom;
  Button cambianom;
  Label cambiarn;

  MiMarco(String title) {
   super(title);
   setLayout(new GridLayout(1,1));
   cambiarn = new Label("New name:");
   newnom = new TextField(24);
   cambianom = new Button("Accept");
   add(cambiarn);
   add(newnom);
   add(cambianom);
  }
 
  public boolean action(Event evt, Object algo) {
   Object target = evt.target;

   if(target == cambianom) {
     nuevoNom = newnom.getText();
     newnom.setText("");
     hide();
    return true;
   }
   
   return false;
  }  
 
 }


In other words, I'd like to use "nuevoNom" String value in public class window3, How do I do that?.

   Thanks a lot.
