well, we could wrap Qt's ones. what this would mean probably is:

making Widget not subclass QGraphicsItem or that matter DataVisualization. it 
would then become, essentially, an interface class for "extra" plasma 
features. so:

namespace Plasma
{
class Label : public QGraphicsItem, public Widget
{
     // implementation of Widget API
};
}

how does that sound?
