Ask the kid and see what her interests really are? Does she want to learn how to make games or what? She should be able to voice this at 12. Can she look up free programming books with Google? There's tons of them. Does she want to mess with a R-PI? If a co-ed camp was a disaster (at the age of 12!) simply because it was co-ed, she might need therapy, not just some hippy-dippy girls-only camp.
