A tool that creates a common GUI for any command-line program
GGUI employs a wizard-like input frontend to collect the information needed.
Then, GGUI automatically calls the desired program with all the necessary options. The user is able to point&click on various options and select them in a convenient way.
To create a new user-interface, you won't need to know a programming language, since there is a graphical editor for new GGUI "scripts".
