A universal fast graphical user interface building tool for arbitrary interpreters

We consider the issue of implementing graphical user interfaces (GUIs): we present an easy-to-use and fast GUI building tool, specially designed to be used with interpreters. It supports a variety of communication methods and interaction models, therefore being able to collaborate with a huge diversity of interpreters in a natural way, in POSIX compliant (or similar) environment. Thus it enables the programmer to easily create a GUI, no matter what kind of language or model the actual interpreter implements. Event-driven programs in UNIX shells and graphical user interfaces in a data oriented language are presented as example applications.
