I need an app making for a Mac

I need to control an app called Wirecast. It's a broadcast tool. It has a playlist feature but no way to schedule them to specific times. They have an API and on Mac they support AppleScript. What I need is something that triggers the playlists at certain times and that a calendar style UI to control it. So it's easy to say play this show at 9am then switch to this one at 10am etc
