Also check out Clarity Ferm. Its not FDA approved to reduce to FDA's definition of "Gluten Free", but it will typically drop out enough glutens (almost all of them) to avoid reaction unless it is a really serious/intense allergy if I understand correctly.
This way you can avoid brewing with sorgum, quinoa, and other equivalent PITAs, and just make any recipe you find, including Sam Adams Summer clones.
Since it is someone you care about, you may want to run some of the research/approximate dissolved glutens by her gastorenterologist/internist to see if he/she buys it.
You could also brew a batch, treat it with Clarity Ferm, and send it to a lab to check.
If you can pull this off (a distinct possibility), your stock is going through the roof.
