I would say "keep it relevant." Consider a number of different scenarios important to her, things she can relate to and learn from. Some example applications:

• A simple contact manager for tracking email addresses, phone numbers, birthdays, and other tidbits. This lets you lead into the rudiments of database theory, SQL, reporting, and so on.

• A "wish list" application for tracking gift ideas, one that allows people to log in, locate an appropriate gift for a person, and then "reserve" it (to prevent multiple people from sending the same gift). This gives you authentication, cookies, and more database design opportunities. (Naturally, the recipient can't see who reserves a gift or even if it's been reserved.)

• If she's into any form of competive sports, perhaps a stastistic tracking thing.

• If she collects anything (comic books, glass figures, whatever), then a catalog system, perhaps, one with ties to the wishlist.

• If she's into astrononmy, then perhaps a viewing log.

• and so on...

In other words, identify programs that she'd find useful, relevant, and interesting, and then design the course to lead to their development. Also, get her input. I'll bet she'll enjoy the collaboration. In turn, this should generate enthusiasm and additional commitment.

In turn, make these deliverables, with milestones, requirements, documentation, and pay-offs for hitting the goals. These don't necessarily have to be monetary, but they should be tangible. Perhaps you do her chores for a week or something similar.

In addition, make sure she knows your responsibilities and that you have milestones of your own.
