The tools/cstester is doing something similar. Please note that there I don't 
use the QWidgets to render the things into QPixmap but render it directly to 
QPixmaps. However the usage of QPixmaps sometimes puts a hight load on the 
xserver as all the pixmaps are transfered to the graphics memory. I plan to 
change that to generate the images using QImage instead which should solve 
this problem.
Please not that for spreadsheers I only paint the the first page into a pixmap.

I see no problem it it is e.g. added to the  tools directory in case you will 
continue to maintain it.
