Good idea. Go for it and let us know what issues you have, then we can help you. This is pretty straightforward, so I think you can do it with a little elbow grease. If you get stuck, let me know, and I'll answer right away.
If you need a hint to get started, then use conditional formatting on the section properties (display tab) and base their behavior off the values of the radio buttons. May want to use checkboxes instead of radio buttons, though, since radio buttons are mutually exclusive and can't be "unchecked."
