In this talk I present a Graphical User Interface (GUI) for a simulator of the Coordination Language Reo, implemented in C++ using the Qt graphical libraries.

After briefly recalling some Reo concepts, I summarize the necessary features such a GUI should offer and mark those that are already implemented. I give an impression on how to work with the tool by showing some screen shots of the application. Moreover, using a UML diagram, I sketch the internal design of the application. I finish by outlining further steps to be done in this project in the coming months.
