This is my first release with win32 api, I couldn't post it in binaries section as it requires 100 post,, so anyway...
Here's what I have:
It is a window, when the mouse touches it, it runs away, if you manage to hit the X to close it you win 
DON'T CHEAT!

Edit: If you've noticed that sometimes the window moves by itself without having to touch it with the mouse is because everytime the window gets a message it executes the movewindow() function in the message loop, and messages can be sent by the OS to the window too, so everytime time the window recieves a message it will always make a movement.
