Programs that control light switches.

[matrix8845]

Does anyone know or have any experiences in writing programs that are used in controlling switches? I am interested in writing a program that controls light switches in a snooker house. Please share with me the areas I need to research on because I really have no idea how to create the interface between the program and the actual light switch.
