A system dynamically constructs a graphical user interface associated with an application. A command class library stores command classes that represent additional functions to be integrated with the application. An execution unit attempts to instantiate the command classes at run-time of the application, determines which of the command classes were instantiated successfully, and constructs the graphical user interface for the application such that the graphical user interface contains the additional functions of the successfully instantiated command classes.
