A few:
Overlapping QLabels is not a good idea - you may get very weird effects next
time anything changes in the implementation or next time you port to a new
system.
Create a pixmap and paint the icon and the text over it. Once you've done that
for the first time it becomes very easy.
Some untested code:
//load the icon
QPixmap pix("/my/iconfile.png");
//enable painting
QPainter paint(&pix);
//draw the text
paint.begin();
paint.drawText(MY_X,MY_Y,"my text");
paint.end();
//create the label
QLabel *mylabel=new QLabel(...);
mylabel->setPixmap(pix);
