creating a custom widget with pyGTK

I'm working on a desktop app for Gnome.

I thought I'd write my own widget to display the results, and since I had made rapid progress with python, I figured I'd stick with it.

After a hour or so looking around the web, I found an excellent tutorial on extending GTK.Widget with Python:
http://www.learningpython.com/2006/07/25/writing-a-custom-widget-using-pygtk/
and subsequently found a link to some demo code on the gnome website:
http://git.gnome.org/cgit/pygtk/tree/examples/gtk/widget.py

So, now I'm armed with these resources, I can get hacking!
Next post: the results!
