利用GUI编程完成以下界面的显示和功能。
建议题主先画出基本界面，随后有问题再交流，先用基本的Swing组件画出界面
用Swing,JMenuBar,JMenu,JMenuItem等类实现菜单。
主窗口菜单界面

import javax.swing.JOptionPane;
import javax.swing.KeyStroke;
/*
* 下拉菜单：
* 1.菜单条(JMenuBar):菜单条有多个子菜单
* 2.子菜单(JMenu):子菜单可以有多个菜单项
* 3.菜单项(JMenuItem)
* 菜单事件:
* ActionListener
*
* 3种对话框：
* 1.(警告对话框)showMessageDialog
* 2.（确认对话框）showConfirmDialog
* 3.(输入对话框)showInputDialog
* */
