Ask and Help Systems ( Desktop/stand alone application)

Problem statement 1. We got several new member in IT support department. The new member always need to ask help from senior which sit sometimes far away from them. Sometimes, the seniors are busy and cannot help the new members. Since the majority of problem need the seniors to come to the new members desk, it will such a disturb when the seniors got something to do. Solution I would like to develop help notifier systems. The new members can press button to ask for help. It will notify the senior which are available. The senior can accept the request and directly come to the new members to help. Surely they need to login to the system using their username.
