Have you considered LyX? Designed for people with a problem like yours - wanting the benefit of TeX output without the effort needed to learn something new. It's also a pretty good structure oriented (rather than WYSIWYG) editor.

Isn't LyX WYSIWYG ? Personally I would say it is. (and also @vancomycin below). Sure there is also the "WYSIWYM" category, but it's more of a pun and not broadly known.

[Paul_S]

LyX is not WYSIWYG and I'm not sure how to argue this point. What you see in the editor window doesn't look like the paginated output - it's not really up to someone's opinion to decide.

[partoutok]

It's not the paginated output but it's close, especially compared to LaTeX code. And I believe many people understand WYSIWYG broadly as a point and click interface with visual feedback, in contrast to writing some code.
