Wix is a terrible answer, their business model is built around ripping off the ignorant, as far as I can tell. For example they'll charge you $150 for a domain name, and their service offers no method of exporting your website when you eventually decide to get a real host.

I can't speak to the quality of Weebly or Squarespace but I'd never use them, the cost is a few bucks more per month than a Wordpress site and I don't see how their services add any value for that extra cost.
