[python-win32] Is it possible to write a python app running at background on Windows?

[A.TNG]

Hi,

I'm looking for a way to write a python app running at background on Windows.

Like some Instant Messenger applications, the app may have a main
windows. When user click "close", main window disappears. But the app
still runs. If user press some key combo, it may active the app and
main window shows again. Since the app runs on Windows and there are
many similar apps nowadays, I think It may not so difficult.

Is there any nice guy could offer some code snippet or some open
source project. So, I could find some hint there.

Thanks in advance.
