Keymaster, BA♮!

My friend Jerry mentioned a problem his trumpet teacher has, and inquired as to whether I could write a computer program to solve it.

Since it looked like an interesting yet simple task, and I have been wanting to try out Qt4 anyway for cross-platform Linux/Windows/Mac GUI applications development, I told him I'd give it a shot.

He had hoped to give it to him as Christmas gift, but I told him that was not very likely… instead, even though his requirements were simple, I expected that together feature creep, the difficulty of learning a completely new widget toolkit, and my rusty C++ would push the delivery date well into the new year.

I was wrong. Within the first 48 hours, I have most of the core functionality, as well as a slick installer for Windows.
