In my opinion, you have two alternatives -- typesetting commands or pulling down menus.
To me, pulling down menus is easier to get started, but becomes increasingly tedious and slow.
With that in mind, have you considered a GUI front-end for LaTeX that provides pull-down capability, like WinEDT? I think WinEDT, coupled with LaTeX, is very easy to learn.
Commands are better, even if they require a little memory on part of the user. And there is no better command-driven typesetting utiltiy than LaTeX.
And if it takes some time to learn, so what? Isn't that time well spent?
