So, maybe Widget is a Layoutitem? Maybe inheriting from QGraphicsItem and 
LayoutItem will make the item a widget?

class Widget : public QGraphicsItem, public LayoutItem
{
};

Just a thought. The approach we're looking at in Qt is that layouts are items 
as well, so the layout hierarchy is the same as the item hierarchy (as 
opposed to with QWidget, where the hierarchy is separate).
