[GUI] Port library for Mac OS X

I've had a look at the Port library, and I think I like it. It looks as if it won't be too difficult to port it to Mac OS X - I'll see what I can do to make it happen. Of course, there's the ever-present menu bar issue (on Mac OS, a menu bar is associated with an application, not with a window). I'll try to work around that somehow. Are there some simple example programs implemented using the Port library that I could use for testing my implementation? I've got some exams coming up in the next two weeks, so I don't know how much time I'll really have, so don't expect results too soon. Cheers, Wolfgang
