LyX

LyX is a graphical front to the very capable L^ATEX page description language. L^ATEXis really a programming language that enables you to do almost anything you could think off, with the added advantage that the output of L^ATEXis device independent. That is, no matter where you print it or how you view it, it will look exactly the same (within the hardware limitations of the printing or viewing device). But it is hard to learn. With Lyx you can easily access a subset of L^ATEXby using a GUI. You will not see the exact rendering of the document in the Lyx window but it is very easy to render to dvi (the native output format of latex) or postscript. Lyx is described as a "WYSIWYM" editor (what you see is what you mean :-)
