I agree with nicola.mfb on the 2 objectives.
The idea with the beginners is a good one, though a bit hard to define who is a beginner and who isn't. I would probably consider myself as a beginner. I'm a professional developer, but I've never made an app for a mobile device, nor one in QT/GTK. I made a port of a game for N900 (see my signature), I don't think that makes me too experienced though.
About the prices for apps from the wishlist..
