In previous works, we have made the proposal of, firstly , a new style of interaction called Goals Driven
Interaction (GDI), specially appropriate for those software applications in which a zero learning time is
necessary, and secondly , a methodology and a notation for the specification of these Goals Driven user
Interfaces. Now, we introduce a software tool which brings support and facilitate the design and the
specification of this type of user interfaces, using that specialized methodology and notation. In addition, the
tool generates the corresponding prototype, from a model or specification made previously.
