So you want icons on sides skewed like they would be rotated?
It can be done without real 3d features with a bit of coordinates computation it can be emulated on transformed() pixmaps.
QSlider is not best base widget i think. I suggest a completely custom widget that inherits QWidget & QButtonGroup, you can add then a number of buttons & your widgets draws them in a 3d-like circle. It's reusable then...
