How to code a Lotto

So I'm new to coding and still in the very experimental stage with what I hope to do, I was wondering if it's possible to set up a lotto that draws from a list of flagged names. Basically certain actions would place these names into the pool and be drawn at random at some point, but I'm not at all sure how to manage that.

I've been mostly experimenting with sugar cube 2 so far.
