Listing entities (vertical) vs. dates (horizontal) with the Calendar module

I'm trying to make a workshift scheduling system with Calendar, and I want it to look kind of like this:

As you can see, users are listed vertically and dates on top.

Is it possible to do something like this with Calendar?

If not, does anybody have any links on how I would begin to develop my own module for this? I can do some PHP, I just need a place to start.

Many thanks!
