Also, you can drop Qt almost completely for wanting its window creation 

I've got a bunch of other projects, image, model loading, scene graph. 
Google Material design GUI toolkit but it is a LONG way off.
I also have started (locally) a new GUI toolkit that uses the Buffer2D 
context instead of OpenGL.

And yes, Devisualization.Window works on the three big platforms.
