请用组合设计模式编写程序，打印输出图 1 的窗口，窗口组件的树结构如图 2 所示，打印输出示例参考图 3。

输入结果如下：

print WinForm(WINDOW 窗口)

print Picture(LOGO 图片)

print Button(登录)

print Button(注册)

print Frame(FRAME1)

print Label(用户名)

print TextBox(文本框)

print Label(密码)

print PasswordBox(密码框)

print CheckBox(复选框)

print TextBox(记住用户名)

print LinkLabel(忘记密码)
