You can't do it with check boxes alone.

A common interface for editing lists is with two list boxes, one
containing the available options, and one containing the edited list. 
In addition, there are buttons to add an option to the list, remove an
option, and to move options up or down. Some of this functionality may
also be available by dragging items within and between the list boxes.

If you have the restriction that an option can only appear once,
adding it to the list removes it from the set of available options,
and removing it from the list returns it to the set of available

An example can be found in the Windows XP explorer (file manager), via
the "View -> Toolbars -> Customize..." menu option.
