    The GUI Painter provides the user with a graphical user interface for building own 
    interfaces by interactively assembling widgets and defining the behavior of the widgets.
    The resulting interface specifications can be saved as methods on the application
    classes, typically subclasses of the class ApplicationModel. These specifications
    are used by the UIBuilder to generate the application window and its widgets when 
    opening the application.
