Note: Due to the lack of time posed by real life, this project has almost become dead.
SQLiteGTK is a very simple GTK+ GUI frontend to SQLite3. It was made by me as an attempt to learn GTK+/SQLite programming. Written in C, current dependencies include GTK+, SQLite3 and GTKSourceView.
Version 0.0.1, a basic functioning version of this project is available. It is not particularly fully fledged with features, but it works. Grab it off SVN branch. The make file is currently Linux only. However, it should be fairly simple to tweak it to compile on Windows.
The development on 0.0.2 has started which includes a huge overhaul to the modular structure of the program. This essentially broke everything and I am currently fixing it. As a result, the code in the SVN is not in a working state at the moment. Needless to say, the overhaul was needed to make the code better and C90 compliant.
