nah, i wouldn't say notepad, cause it's not in Linux...it's all about vim for web-editing
but seriously...the two i keep hearing are bluefish and coffeecup. i've never used either one so i can't really say anything about them cause i do everything in code (usually in notepad or pico/kedit), but they're worth a shot
EDIT: wow i'm slow...two posts in front of mine
