That depends on the manipulations that you need to do, and requirements 
of speed for instance.
There are plenty of matrix implementations around, and for a static 4x4 
matrix, it would probably be easy to make it yourself too. I have done 
so... The QMatrix and QTransform classes are really mend for 
projectionmanipulation, nothing more.
For instance, take a look at Eigen (http://eigen.tuxfamily.org/1/) if 
you want something fast.

Or, wait for Qt 4.6 for a 4x4 matrix implementation.
