I don't have much to add about the specific communication devices, but what I will add is to look in the social aspect of gmrs or ham. Are there repeaters for either locally, is there a ham club, or at least a group that meets near her location. I don't have a gmrs radio but I learned about the local gmrs repeaters from the local ham group. One of the local groups does a nightly check-in,training net. Having a friendly group of like minded people might give her enough enthusiasm to get licensed. I'm fortunate that where I'm at there are several clubs that are very welcoming of new members and are willing to help someone new to the hobby. If you can talk her into that she may have a new group of friends that are not only nice people but willing to help her if she needs it.
