绝对有挑战性的问题：如何将Form整到桌面上？ ( 积分: 50 )

实现这样的功能：
1、该Form整到桌面，就和主程序没有什么关系了。当然，主程序关闭，这个桌面Form也要关闭，实在无法关闭该桌面Form也没有关系。
2、该Form实现类似于QQ那样的隐藏/显示效果，就是鼠标点上去的时候，就列出来了，移开鼠标，Form就跑到上面去了，节约空间。Form显示时是在最前面的窗口（QQ显示时也在最前面）
3、为什么需要这个Form呢？因为正个主程序，该Form使用的频率最高，这样设计的话，客户用起来就比较方便。
欢迎各位大侠出手！万分感谢！

这个很弱智的，能挑战谁，网上大把例子，比这个要求还要复杂都有，而且很旧。
