Have a look at something like this FIRST:
http://www.weebly.com
[it's free, you can build quite a functional and professional site in minutes ].
Now weebly is not the only service of its kind, it's just the one i've used recently. The free service doesn't have any ads and you can get pretty far. Even if you use it to make a CONCEPT SITE , i suggest try it...nothing to lose . You basically get a bunch of pre-definied modules which you drag and drop on your site [forum/shopping carts/guestbooks/video/audio etc].
Places like Hetzner [local] and Godaddy.com offer similar "site builders" , but you pay for it and usually you can combine this with your own code [something weebly don't quite do].
I know Godaddy.com gives you a very nice site builder equal if not better to weebly which you can quickly roll out instantly and then you can go and code your own database related stuff if your site actually needs it.
And if you're into a more VISUAL/MEDIA site requirement...check out
http://www.wix.com . You build a flash site, main emphasis is on graphics and animations..so it works awesome if you're building a photography type of site that needs some special touches
Main reason i recommend these things? If you build a site with your own code = YOU are going to be the sucker that needs to maintain it FOREVER. This is especially the case if you're doing it for family...trust me, give them a tool to do it themselves.....or at least allows you to do it easily.
