If there are >2 applications demanding this, it might be a good idea. But 
there are easy ways to do this. See my prototype implementation (it still 
lacks resizing and I probably want built-in tooltips and the "..." style for 
texts too long to fit. Here's my complete prototype implementation (the only 
tricky part is giving the x- and y-Positions, due to the coordinate 
transformation):

VerticalText::VerticalText(QWidget * parent, const char * name, WFlags f) : 
QWidget(parent,name,f)
{
        resize(20,100 /*parent->height() */ );
        setFixedSize(20,100);
}

VerticalText::~VerticalText() {
}

void VerticalText::paintEvent ( QPaintEvent * /*event*/ ) {
        QPainter paint(this);
        paint.rotate(270);
        paint.drawText(-height()+2,width(),name());
}
