wxPython API docs. I recommend that you refer to these throughout the tutorial:
This tutorial is written from a Linux user's perspective. wxGlade is a visual application that produces a wxPython framework (http://wxglade.sourceforge.net/). I am writing this as I learn, so there may be some mistakes and misunderstandings. The level of explanation may be minimal in some places, but the code exerpts should compensate for this. Please add comments to the bottom of the pages.
