Thanks for everyone's replies, I found airtable to be nice and simple for people who want to use a database, fieldbookapp a bit higher end, and APEX too confusing.
However I still can't see how to do the "getting started with SQL" type stuff, for people who don't want to use the command line for everything, but still want to use SQL in not too complex ways, maybe a more friendly version of phpmyadmin (and friends).
