thread doesn't execute

I'm new in java, so i guess it's a simple problem. In my event listener i have a method which declares variables and i'm trying to use those variables in thread which i use in same event. Although it does not work, here is the code:

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

public class GUI extends Frame implements WindowListener,ActionListener {
cpWindow window1 = new cpWindow();
cmWindow window2 = new cmWindow();
SolarSystem system = new SolarSystem(300,300);
Planet Planetarium;
/**
* Frame for general window.
*/
public void createFrame0(){
JFrame f0 = new JFrame("Choose what you want to do");
f0.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f0.addWindowListener(this);
f0.setLayout(new GridLayout(3,1));
JButton cP = new JButton("Create a planet");
JButton cM = new JButton("Create a moon");
JButton Delete = new JButton("Delete a planet or moon");
f0.add(cP);
f0.add(cM);
f0.add(Delete);
cP.addActionListener(this);
cM.addActionListener(this);
Delete.addActionListener(this);
cP.setActionCommand("1");
cM.setActionCommand("2");
Delete.setActionCommand("3");
f0.pack();
f0.setVisible(true);
}

}

any ideas?

One needs to actually start the Thread, just instantiating a Thread object is not enough.

public void actionPerformed(ActionEvent e) {
    createVariables();
    new NewThread().start();
}

When you create a Thread with new Thread(), you have to pass an instance of Runnable that contains the actual code you want to execute in the thread.

So your constructor of NewThread should look like

NewThread() {
  // Create a new, second thread
  t = new Thread(this);
  t.start(); // Start the thread
}

This will create a thread that executes the code in NewThread#run(), which I guess is what you want.

Be sure to finish any necessary initialization of the fields in NewThread before doing this.
