Two years ago or so I was working on this already, you can find the results 

It is a back then up-to-date copy of Microwindows. It supports the Qt virtual 
frame buffer, and it shouldn't be hard to port it to the new framebuffer 
support in eCos.
It can be configured fine-grained, e.g. you can enable only the drawing 
functions, then you get a library for drawing, which doesn't require any 
mwin, the Windows compatible API works, it also doesn't need networking 
(tested with Qvfb and on an ARM board).
I didn't manage to rip the network requirements out of the X API yet, so this 
still needs to be done. 
A socket is used for communication with the X server thread, it should be 
possible to replace this with eCos thread synchronization primitives.

Most of my changes are also in the main Microwindows cvs.
