Technology challenged grandpa was set loose on the internet

I (ancient male U.S.) am setting up a new website for the scout troop. I have a domain name, purchased through NameCheap, and a functioning Google Site. I'm trying to connect the two and the terminology and verbiage has my low-tech head spinning. Is there a source that has a step-by-step guide written at a 7-year old's comprehension level?
