You can definitely do custom paint event in QWidget. The only reason I decided to suggest QGraphics is because when you start having a view with a huge number of QWidgets, it can get slow. This is because each QWidget individually manages a lot more of its own geometry and painting, where as QGraphicsScene has a much more efficient process for doing painting and overall management, with lighter weight objects.
I think, for instance, if I had tried to lay out my visual EDL diff application with QWidgets, the scrolling of the timelines would have been really slow, as each timeline could have 300-400 shot items, and you can have an arbitrary number of timelines.
