With a friend we created the DQuick project cause of our major interest 
of the QtQuick (also called QML) part of Qt framework and also for the 
reason you invoke. For us phobos already aim to implement same things 
than QtCore, and wrapping primitive types of Qt seems hard and will 
introduce design constraint and poor performances. It's certainly bad 
for a longterm vision.

IMO DQt will be interesting for those looking for a stable GUI library 
based on widget essentially.
DQuick have no chance to be usable in production before years if we 
continue to develop it.
We are back after a long break, it's really hard to stay motivated cause 
we have some difficulties with points aren't fixed in D, mainly GC 
issues, signals,... My friend just find get the property binding working 
in D code, but he doesn't like his code :-).

I see DQt/gtkD and DQuick as complementary projects. I hope we will 
capable to provide good enough GUI libraries to D community shortly.
