Why isn't there a MS Word for creating HTML?
The typical problem with WYSIWYG webpage builders is that the web is not a printed document. If you don't know the underlying concepts of layout you expect things to behave much differently than they actually do. Or at least, that was how it was for me.
One of my earliest memories of 'coding' (It seems silly to call it that now, but hey, I was 13!) was opening the generated html files to remove the "Created with Frontpage" html comments that were automatically injected.
