OK, looks like I am getting a Mac for pen testing (more on that in another post), so I started thinking about cross platform GUI development (again). I had all intentions of using the browser as the GUI but sometimes that just sucks.

So I was seeing whats available for doing GUI's on the Mac when I can across this article on using JRuby and SWT. JRuby is a Ruby interpreter written entirely in Java, with full access to all the Java classes. SWT is the Standard Widget Toolkit used as the GUI library by the Eclipse IDE (sponsored by IBM). SWT looks so promising as it uses native widgets, there is also a GUI builder called SWeeT GUI.
