**Easiest** way to run Minecraft Create?

So, I'm the kind of player that comes back to minecraft every few months/years, and get tired and stop playing over and over. Because of this I don't have the energy to spend five hours setting up various custom launchers with various manual downloads & installations & configs etc.

I just want an easy, straightforward way to check out the Minecraft Create mod. I have a legit copy of the game if that's the easiest way, but if the easier method involves other copies that's fine; the laws in my country mean that since I've bought it (back in Alpha, even!), using other copies of the software isn't considered "pirating".
