QtCreator is fine for creating Qt code, but the thing missing is easy running configuration for your apps in scratchbox from QtCreator. Right now I think the only way to do this is manually and it can be hard for someone new to all of this. I too think this is something that those making documentation and tools should concentrate on. I am sure there are many of us that haven't done maemo development before and probably are using windows as well as their main OS. Learning Qt isn't the problem, it is how to setup everything that seems to be the hardest part right now.
