Good question.
What you could perhaps do, is to create your own widget that groups the 
radio buttons (perhaps a QGroupBox derived class?), and that 
encapsulates a QButtonGroup. If you give it a property to read/write a 
single value that represents/sets which button is currently selected, 
you should be able to use that with a QDataWidgetMapper. You can not use 
a QButtonGroup directly, as it is not a QWidget.

I did not try that myself.
