JButton, actionlistener, that works!!!!!!

Question

As I said I have looked endlessly through tutorials and found everything except what I want. All the examples have been applets and I
have a JFrame with a JButton in it. ALL I WANT TO DO....Is make the button have an action (click on button - "Yo" is printed)
This seems impossible to me, surely someone here must know how to do it.... anyway here is what I have...
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class action extends JFrame implements ActionListener {
public JFrame window = new JFrame("window title");
public action(String text)
Toolkit theKit = window.getToolkit();
window.setBounds(400,400,400,400); //get toolkit / set bounds
GridLayout grid = new GridLayout(1,1); // set up simple grid
Container content = window.getContentPane(); // prepare content (container)
content.setLayout(grid); // set grid
JButton button = new JButton("Button"); // draw button
button.addActionListener(this); // set up listener
public void actionPerformed(ActionEvent e) { // actionEvent to be triggered when button pressed
System.out.println("It WORKED!!!!!!!!!!!!!!! GO TAMPA BAY!!");
When I do this I get this error no matter what I try!!!
Exception in thread "main" java.lang.NoSuchMethodError: main
Anyone know how I can make this work, thanks!!

You're getting the main error message because when you run a Java application, it's looking for the main method, which you don't have.
Here's a sample JFrame:
import java.awt.event.*;
import javax.swing.*;
public MyFrame extends JFrame implements ActionListener {
     public MyFrame() {
          JButton button = new JButton("OK");
          this.getContentPane().add(button);
          button.addActionListener(this);
          this.setSize(400, 300);
          this.setVisible(true);
          this.setDefaultCloseOpeartion(JFrame.EXIT_ON_CLOSE);
     public static void main(String[] args) {
          new MyFrame();
     public void actionPerformed(ActionEvent e) {
          System.out.println("Click");
}
