SQLite Visual Web-Based Content Editor App

[Hentai]

I'm developing an Android application that requires alot of data to get started. I've created a SQLite database, but need to get people to help me populate the DB with data. I'd like to do this via a web-based interface.Of course i can build my own, but that would be a waste of time if one already exists that could accomplish what i need. Here's what i need:

• Ability to add new records to a table
• Fields with foreign keys should provide a dropdown of options from the joined table
• Fields with many-to-many relationships to other tables should provide option to select multiple records from the joined table

I guess I'll probably need to build my own app to do this, but if anybody can point me in the direction of one that already exists, that'd be awesome. Otherwise perhaps links to .Net frameworks that could provide a starting point for this development?
