It does? If memory serves me signals and slots are not realtime safe, moreover 
they are only allowed to be used from one thread. Hence, if you have a GUI 
only that thread can utilize these features.

I don't see why Qt is a bad dependency, on the contrary, having it all in one 
place seems like a very good way to cut down on dependencies. 
Since it's mostly used as a shared library the impact becomes much smaller as 
soon as you use more than one program linked to Qt.

Though, if I'm right about the above, it might be the totally wrong choice.
