Ações em Java

Bom dia… Alguem poderia me ajudar… pois estou desenvolvendo um compilador e não consigo colocar as ações de abrir e fechar nos botões. Quem souber por favor poderia me passar o código. Estou utilizando o programa IDE NetBeans 6.1.

Obrigada!!

Eis aí o codigo:

package com.compilador.view;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileWriter;

import java.io.IOException;

import javax.swing.JOptionPane;

/**

*/
public class Editor extends javax.swing.JFrame {

/** Creates new form JanelaPrincipal */

public Editor() {

initComponents();

init();

}

private void init() {

editor.setTabSize(1);

mensagem.setTabSize(1);

}

/** This method is called from within the constructor to

initialize the form.
WARNING: Do NOT modify this code. The content of this method is

always regenerated by the Form Editor.
