Hi all!!!
Here in Italy there's a new project called BUC (Basta un Click, Just a click, in english) for linux, it's an interpreter of Bash and it uses XML language to create scripts with a GUI.
Unfortunately the wiki page is only in Italian. If someone is interested, i can translate it to english.
It's a very simple language and can be useful when you need a quick GUI for a terminal program or similar.
Bye
