Sorry to be the bearer of bad news, but most "easy" web design programs won't automatically guarantee you a "great" page (although your definition of "great" may well differ from mine
) - usually the opposite, in fact.
Unfortunately with web design (as with so much else in life) the more you put in, the more you get out. You say you're a graphic designer so you've already got an advantage over some web designers (who may know all the code but have no idea of what constitutes "good" graphic design) - take the time to learn HTML, CSS, PHP etc. rather than relying on some "website-by-numbers" package to write the code for you and I'm sure you'll end up with a truly "great" site.
