When you create the widget button-group, use the keyword IDS to
return a lonarr containing the widget id's of the individual
buttons in the group:

bgroup1 = cw_bgroup( tlb, ..., ids = ids_grp1, ...)

Then use widget_control on these individual button widgets:

widget_control, ids_grp1(0), set_button=1
widget_control, ids_grp1(1), set_button=0
...
