Qt 5 is supposed to be mostly source code compatible with Qt 4. The 
exceptions are supposed to be highlighted in dist/changes-5.0.0 in the 
source tree.

You should probably ask separately about qwt with qt5. I don't know.

There is an alpha release. Beta is expected soon. Or just clone the git 
repo.  See http://qt-project.org/wiki/Qt_5.0.

No personal experience here, but it should work. If you run into 
problems, this is a good time to get them fixed.
