I usually slap my stuff together visually quick, then clean and tweak in Notepad and validate at the WC3 site or use the MX validation toolset

Though, keep in mind that once you go down the route of learning html/asp/css, whatever, you will rely less, and less on visual apps, and find it easier, and in some cases faster to do it by hand...
Took me a LONG time, but I got there doing it that way

Personal preference either-way I think.
