There is disclosed a technique for creating a plug and play interface for user actions on a graphical user interface (GUI) on a computer system such as might be used in a client-server network. A text file is prepared in XML language containing all possible user actions. The text file is read by GUI framework application software running on the operating system, and the results are stored in at least one table as Java code. The framework application software calls the Java code in response to user requests. The technique lends itself to modularization and therefore to ease of manufacture of such software plug and play interface. Such software can be easily modified at any time up to runtime.
