Seedlet is an easy-to-embed source-code-embedded Java GUI for programs whose GUI requirements are simple. It is designed to provide a fast, flexible and simple GUI without a lot of work developing it.
Seedlet is AWT-based and, besides the GUI, contains a lot of machinery 'under the hood' to simplify application development. It was written to be used (but not limited to) three ways:
To this end, Seedlet includes a LOT of equipment not necessarily GUI-related. Besides the main class, it has ancillary tools for XML, JDBC, file processing and logging. GUI-wise, it provides pre-made panels for handling scripting, macros, alternate ClassLoaders, JDBC and templating. Best of all, it's FREE! Free as in speech and free as in pizza. Just download it, snap it on and your GUI is handled.
