Please consider the lightweight canvas widget by Maurizio Monge: it is halfway between using a raw QPainter and the unneeded complexity of QGV. He wrote about it some weeks ago in this very mailing list.
We (Maurizio and I) are using it for the chess interface KBoard (http://kboard.sourceforge.net) with great satisfaction. It is fast (unless you need to manage millions of sprites, but that's not the case, I suppose), easy to use and stable (KBoard is quite a stress test for it, and we haven't found bugs for months).
You can read more about it and download it here: http://kboard.sourceforge.net/wiki/index.php/Canvas
