As has already been said before, Wix is extremely closed of a system, and falls into the realm of "pretty to look at" but that's where the positives and and the laundry list of negatives begin - it's code is ridiculously messy and very unfriendly for SEO (meaning Google, Bing etc will be less likely to index you or, if they do, you won't rank), and it's so restrictive that you can't even change your mind about your theme later or give your site a "facelift" by updating your theme, or modernizing it. It would require you to START OVER FROM SCRATCH - there's no excuse for that. Also, it's extremely expensive (in the long run).
WordPress is by far your best (and cheapest), and most flexible option long term. If you are BELIGERANTLY opposed to learning WordPress, I would suggest Weebly (MUCH better coded than Wix, better for SEO, better for customization/site changes, and if you decide to make any major changes with the help of a developer, you have full access to the HTML & CSS...
Just my 2 cents
