Forget DreamWeaver and go with WordPress so that the site can be maintained by the client. Unless you wish to be bothered without payment by your relative you can offload maintenance and changes to the client with WordPress.
Or joomla (haven't tried wordpress).
I dunno. For a 'flat' site that is unlikely to be updated very often, a cms could be overkill by a factor of 10,000.
"bothered without payment" this is the key, isn't it?
Somehow, the non-paying relative's priorities are always eclipsed by more rewarding pastimes, like watching tv in your underwear...
