If you reached this point, you have a strong understanding of the benefits and difficulties of model-view programming. If you compare your application to something like juK or amaroK, you can come up with ideas for other features to add. This might be a good time to download and examine source code of these and other existing KDE projectsyou will notice most of them are Qt 3 based, and you should be able to understand the code now. If you feel confident enough, you might want to help in the maintenance or porting of existing KDE projects over to Qt 4 / KDE4. Join the mailing lists for your favorite projects.
