Simple .exe Popup Application

I need a simple application used to notify end users when a remote administration session has ended. The application need to be a .exe that launches a window that reads "Support Team has completed task" and play a default sound. The window should have an OK button to acknoledge and close. The application should also close by itself after 10 minutes. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows 2K, XP, 98.
