simplify frontend logic

[Andre Poenitz]

I plan to 'manually expand' the current uses QController as in the
attached patch.

The result is not only shorter but also simpler. No need for a template
with a template argument (QController) anymore.

Maybe I'll arrive at a point where I understand the code at some time...
