Griffon

Griffon is a Grails like application framework for developing desktop applications in Groovy. Inspired by Grails, Griffon follows the Convention over Configuration paradigm, paired with an intuitive MVC architecture and a command line interface. Griffon also follows the spirit of the Swing Application Framework (JSR 296), it defines a simple yet powerful application life cycle and event publishing mechanism. Another interesting feature comes from the Groovy language itself: automatic property support and property binding (inspired by BeansBinding (JSR 295)), which makes creating observable beans and binding to their properties a snap! As if property binding was not enough Groovy's SwingBuilder also simplifies building multi-threaded applications, say goodbye to the ugly gray rectangle (the bane of Swing apps)!
