Didn't do the rotation handles but did implement the resize handles.

 I did it by subclassing from QGraphicsPolygonItem and overriding a bunch of
the methods:
 virtual void contextMenuEvent(QGraphicsSceneContextMenuEvent *event);
    virtual void mouseMoveEvent(QGraphicsSceneMouseEvent *event);
    virtual void hoverMoveEvent(QGraphicsSceneHoverEvent *event);
    virtual void mousePressEvent(QGraphicsSceneMouseEvent *event);
    virtual void mouseDoubleClickEvent (QGraphicsSceneMouseEvent *event);
    virtual void mouseReleaseEvent(QGraphicsSceneMouseEvent *event);
    virtual void keyPressEvent(QKeyEvent *event);
    CTRL_POINTS isInResizeArea(const QPointF &pos);

And also implemented my own paint method. The source code is at:
