Recipients dependant on user selection of radio button

Hi Folks,
Rather than produce a plethora of contact forms I was wondering if there is a way that the recipient can be governed by the selection of a radio button field on the form.
Ie…”Who do you wish to contact?” button one Membership; button two Treasurer; button 3 etc etc.
If this can be done is there a tutorial on how to do this.
Thanks in advance,
Eugene Stevenson.
