A static Qt and VTK should work.  I just tried on Linux and it worked.

I suggest, you check your Qt build against the Qt examples to see if you get 
unresolved references.  If you have problems, you could go to the Qt list for 
help.
Then introduce VTK.  If you start having problems when VTK is introduced, then 
you can give us the link errors you are seeing.
