Having gone that route word -> latex -> html; i've converged to using an Open source desktop publishing app called Scribus [0]. You get WYSIWYG, but on an open format. There wasn't anything fancy to learn on the tool. The app is actually used to all kinds of magazines and books, so a resume is pretty simple compared to those.
If you need a template to get started, you can use mine here [1]. The output pdf is also in the repo(although haven't updated it in 5 years now!). Reminds me to go and fix/refactor it a bit.
