QT Support for Unreal Engine

As I understand there is no official support for integrating QT C++ libraries with Unreal Engine. I do think that this should be possible since both systems are open source and written in the same language. I also went through some documentation on integrating third party libraries into the Unreal Engine. So my first question is: Has anyone tried this? Do you have pointers? Any points of wisdom?

Second, I have seen some possible integration between QT and UE using Python script. I am wondering if it is possible to bury everything in a single app/program under the same screen layout. Any help on this is appreciated.

Thanks in advance,
