I know that currently there is no support for this in Qt, also no plans
to add it, all I wanted to hear is "It's possible".

I assume it would be only a community-driven long-term project, which takes
years until it is on par with QtWidgets. But hey, I'm fascinated by the idea,
and maybe I'm not alone.

ATM the problem is to get started because I don't know much about the
current architecture of the graphic stack.
Any hints where to start for a first hello world?
