Real Time Mapping of Windows NT Windows Onto an OpenGL object

Hello.

Does anyone know of a tutorial on how to map a Windows NT Window ( say, Microsoft Word, or a clock ) onto an OpenGL object. I would like the tutorial to be real time. AKA: If someone is typing in word, you see the updates ( and preferably the mouse location ) displayed on the side of the OpenGL object.

Thanks,

Patrick

would like fries with that?
