I might have missed something here, but how will you solve the problem of Maemo APIs if you develop with Qt Creator on a desktop platform ? Only the simplest of apps can be developed in Creator and then 'just compiled in SB', and even then, you WILL have ifdefs. Try to access the address book, the desktop, widgets, MAFW, the location framework, accelerometers, cellular or IM functionality and suddently you find yourself in the middle of nowhere... I'd still recommend Python for weekend coders, especially those with C(++)itis. At least with that you can forego the whole SB/SDK thing and still not have the problem above.
