GUI for mapping db tables

[stuart armstrong]

I would like to create a GUI that allows a user to view 2 database tables and then drag and drop mappings - mapping the columns from database 1 to the columns in database 2. Does anyone know of an open source project that does something similar, or any relevant tutorials?

Depends how much SQL you know already. Needless to say, there is something in the Java Tutorials, also about Drag'n'Drop. See whether those are any use to you.
