I don't think that's a problem.
CMake has the same issue itself, you need cmake to build cmake.
So, what you do is you can either bootstrap cmake (then first a stripped down
version of cmake is built, which then builds the full cmake), or use an older
version of cmake to build the new cmake.
The same could be done here.
Use cmake and cmake-gui built against Qt x.y to build Qt x.y+1.
If there is no Qt at all, cmake-gui will not be built, it is optional.
