I made some progress over a year ago in backporting some of the changes from 
Qt 5 to Qt 4.8. But this was prior to Wayland 1.0 and there were some changes 
I never got in.

You can see my branch here:

Probably my branch above. I haven't built it in 15 months, so no warranties.

But please note that QPA in Qt 4.8 is limited by itself. It was missing some 
functionality that a proper Wayland application would need. I really recommend 
you consider Qt 5.

Since QPA was new in Qt 4.8, it means you must have started this project only 
recently. Since you're asking now, 6 months after the Qt 5.0 release (and 5.1 
is approaching), can we ask why the interest?
