That's cool. Actually, most indexes are already stored as some kind of a tree inside of the db; and clustered indexes are b-trees, regular indexes depend on the db system you're using. But then, the SQL standard is set up such that the db handles all the data manip for you and you use the structured query language to retrieve and store the data... It's not like you really need to define your own trees if you're using a good system.
