framework for a databased crossplatform GUI application

I would like to develope a databased GUI application for free, which is cross-platform. I almost decided, that the UI should be GTK (logical, not pixel-based layout, GUI description not cluttering the code (glade xml))...

What I am missing is a good framework, which connects database and GU开发者_Python百科I, so I am looking for building database gui app.

Any suggestions? (ask me for more details if I am not concrete enough)

Consider using Dabo for this. It is a GUI application framework for building apps around a database. It uses wxWindows for the GUI toolkit which is a bit higher level than just GTK. And you write your code in Python.

The natural choice, if GTK+ is used, would be libgda: it provides a quite advanced abstraction layer on more database engines. There is another ongoing project, gsql, but I don't know anything about it and I didn't understand the differences between them either.

Take a look at Glom, seems to do a lot what you want.
