I am part of a commercial windows project. Currently migrating from
KKWidgets to Qt.
I had some troubles building latest VTK6.1 with Qt 4.8.x but I was
successful with Qt5.x-opengl.
Still in the very beginning but need to make the call soon whether to
go this way.

the codebase of scirun4 is one of the finest I have seen !!!

still not aware of more level routines, since you do have quite soe
custom otherwise standart c++std, like threads, but:
i got already two modules implemented myself in scirun4. solving
biot-svart for TMS coil and another for creating predefined coil types
(geometry) co-planner only!
a 3rd one is in a cooking oven, about executing external processes
using http://pstreams.sourceforge.net/
one thing I hate though is TCL/TK and not because of scirun but
KWWidgets and thus looking forward to working with Qt !!!

anyway I will look around and/or maybe compile some list for myself meanwhile.
