Start with HTML, then CSS. If he wants to build his own website, let him do that. Walk him through making a basic page right away (static, unstyled HTML), have him link some together, etc. He will be motivated to learn new tricks as he seeks to improve the pages.

No need to learn javascript or something else at this point. if it's not immediately related to what he wants to do he'll get bored.

You have the right idea with feedback loop. Kids can teach themselves, given the resources. Your main job is to nurture his motivation.
