Why not adding another (maybe hidden?) radiobutton?
This way you haven't to worry:
* The user can "deselect" simply by selecting the "None selected" buton
* If you hide it, you have to programmatically select it (maybe binding 
to keyboard event?) but the interface isn't modified
* you haven't to write a new widget

BUT if it's needed to have a radio group with no selected elements, 
IMVHO there's some deep UI design problem...
