Yup, this is not too hard.  What you want to do is something like this:

myRadio = NewControl(ownerWindow, &boundsRect, "\PYour Title here.",
	TRUE /* visible */,
	1 /* value 1 is set, 0 is clear */,
	0 /* minimum */,
	1 /* maximum */,
	radioButProc /* what type of control */,
	myReference /* refCon */);

If the value is 1, it is set.  If it is zero, it is clear.  If you pull the
control up from a resource file, use SetCtlValue() to change the default.

eg, SetCtlValue(myRadio, 1); /* turn it on */
    SetCtlValue(myRadio, 0); /* turn it off */
