Use something like this:

<input type="radio" name="foo" value="bar2" id="bar2"> <label for="bar2">Bar Two</label>
<input type="radio" name="foo" value="bar3" id="bar3"> <label for="bar3">Bar Three</label>

Use Javascript. Call a method whenever a CheckBox is clicked that takes the ID of that CheckBox as an argument and then unchecks all other Checkboxes in the given context.
