I recommend reading the appropriate chapters in this book: http://www.qtrac.eu/pyqtbook.html and have a look this ressource: http://www.yasinuludag.com/blog/ also download a version of PyQt, it has all original Qt examples (including the model view thingies) translated to python, which helps a lot and is a good starting point.
