In your class diagram you will normally describe/design the (data) model part of your application, while the user interface (UI) corresponds to the view part within a model-view-controller (MVC) architecture. As a UI cannot be designed with a class diagram, I cannot see any meaning for a "UserInterface" class.

However, there is a new modeling language for modeling user interfaces: the Interaction Flow Modeling Language (IFML), which has been adopted as a standard by the OMG in March 2013. If you are serious about UI modeling, then you should use that language.
