Where should I start with game development and UE4?

I say give it a try, as any other option will require you to do some sort of scripting at some level or another.
Coding experience is not required with UE4, but you will want to spend some time in their tutorials to find your way around the editor. You can build games using just blueprint logic, and UE4 has tons of sample blueprints and template projects available when you download the editor. I suggest going here to watch some video tutorials to get started.

Head to the last page, as most recent ones are a bit more advanced.

Hope that helps!
