This is a very good idea. Similar to Rosetta Code for GUIs. They do a good job explaining the task specifications and the attributes of the framework that each task intends to test/reveal. I think they should add a task where events outside the user's control can affect the GUI state in non-trival ways. For example, a control panel for a piece of hardware that could be disconnected at any moment, or a remote file viewer where the server can take away the user's rights to view a file while they are viewing it. This makes GUIs more challenging in my experience.
