The Swing Application Framework that will be part of Java 7 makes developing Java Swing applications easier and helps in avoiding writing boilerplate code such as saving an application Window dimensions, locations, it provides a structured approach to developing Swing application which was lacking apart from the Netbeans platform which has a steep learning curve. For the time being there’s not as much documentation as someone would like to have but it should be straightforward because the framework is small. Coupled with JGoodies FormLayout it’s the best way to create small to midsize Swing applications.
