I tried that already, without much result. It's hard and not very fruitful 
work. Qt is also probably slow and memory-hungry (it's not just a "GUI 
library", it's more like a complete C++ operating system). See:

So I kicked all this away and went for a modded Genode FX 
( which provided the most features and an 
acceptable look and feel (Nano-X demos = jokes) with a small resource 
footprint and relatively little effort.
