go to a website like
http://godaddy.comcreate and account, and look for your prefered domain, and if it's already taken. a domain usually costs within 6-10$, from what I've seen, but I prefer godaddy, so that's just a suggestion. a domain name is just a .com or .net or .org name...you will need hosting if you want your website up, and online.
I recommend looking at
http://dreamhost.com ..they've been my host now for not even a month..and I like them. They don't have cpanel, but their interface is simple and not complicated at all. haha, i paid $10 for their 'crazy domain sale' ..but it's some sort of 'promo code' and I don't think I'd be able to post it without being looked down upon and dubbed a spammer/advertiser..
just google it..
i made the mistake, though, of registering a domain with godaddy to go with a free host like [
http://superfreeweb.com ] and then found dreamhost and they registered
another domain for me...so now I have 2..I didn't want 2, but eh.
