I think that sounds about right. Use GraphicsView
(http://doc.qtsoftware.com/4.5/graphicsview.html ) for the rectangles.
It supports drawing stuff (rectangles, circles, text, widgets...) and
handling mouse events.

As for the textual info, it depends how the text is organized. But
QListView looks like one of the classes you might want to try out.
