Wordpress is the most beginner-friendly solution I know of in terms of fitting together nicely and smoothly. If you're doing it on your own server, you will have to do the Wordpress install yes, but that's true of any solution you pursue, and once the base is in it's very easy to add e-commerce functionality. There are a ton of Youtube tutorials that show the process in varying levels of detail, but this one shows a streamlined way to actually install and set up the Woocommerce plugin. You will have to enter products and etc, but actually installing the plugin is literally about a 30-second process.

I generally like to talk it up just because Wordpress is generally my go-to for easy setup of a new web site, whether or not it involves e-commerce; it's easy and well-supported and dedicated Wordpress hosting is probably some of the cheapest types of hosting you'll be able to find on the internet. That tutorial I linked about likes Bluehost; personally I prefer Tigertech but the point is there are easy and cheap options.

I'm happy to answer questions or help; I've set up a few different little amateur-mode e-commerce sites on Wordpress and I don't know of any easier solution.
