The attribute you are looking for is WS_GROUP. You set this on the first button (in tab-order) of the set of buttons that you want to be linked together and omit it on the rest. The group is 'closed' the next time a button is created with the WS_GROUP flag set.

See Using Radio Buttons for more info.

Note:I don't know how you actually specify this using Win32::GUI. You might find Win32::GUI Window Styles and Transparency useful.
