GUI-Builder:
this class allows the user to build its own applications providing a graphical
user interface to buildin components and to define the behavior of the components
during runtime. The resulting specifications can be installed as methods on
classes, typically subclasses of an ApplicationModel. These specifications
are used by the UIBuilder to generate the application window and its component
structues when open the application.
