Ask Slashdot: easy alternative to MS Access for an easy-to-use DB for a charity?

danzvash writes: I'm doing some volunteering for a street kids charity in Senegal, West Africa, and they need a new database to store all their information for the kids, and to help the funding organisations like UNICEF. The charity staff have a few computers running Windows 7. Being a die-hard OSS geek I'm more inclined to knock up a MySQL backend with a Django (or similar) frontend and run the whole thing from a reliable VPS. But it needs to be understandable by the non-geeks in the charity — there is no IT expertise here. Is there anything that can allow me to design and edit databases, tables, and forms but doesn't require an MS license?
