Sqlkit provides a GUI named sqledit to edit data in a database, as well as a package (sqlkit) in PyGtk. Sqledit (the application) can be run from the command line with arguments and will pop directly into the table/mask of the data, or without arguments and will present an input mask to write the database URL. Sqlkit (the Python package) provides SqlMask and SqlTable, two widgets for editing database data. It is meant to be used as a base for database desktop applications.
