A system and a method for creating user interfaces for software applications. Particularly, the invention allows a developer to segregate the development of the user interface from the development of the underlying application logic. In one embodiment, an application graphical user interface is specified using an XML document as an application interface file. At application compile time this application interface file is parsed, and the specification therein used to retrieve graphical screen components from an interface library to create the user interface. A grammar file can be used to further specify the parsing of the application interface file, and impose consistency upon the interface development process.
