Thanks for the quick reply I'm afraid I don't know much about packaging libraries. As you probably figure I'm pretty new to developing for Maemo (and Debian in general). How would I go ahead to port the packages and push them to the repositories? If you have a look in the sources for zbar-0.10, there is a folder named "qt". I'm not sure what compile options one needs to compile it with the Qt bindings, but they are included in the Debian repos as the package libzbarqt-dev.
