GUI Wake-Up Call

Does anyone have the ability to use the API to create a GUI interface to set a wake-up call? I would love to see something that could perhaps mimic the operator panel to create the functionality.

As much as I dislike 3CX, two things that system does very elegantly is wake-up calls and PMS integration. I am open to ideas and I fully expect to compensate the individual for their effort. Is anyone able and interested?
