Professional web development tools for Linux?

Hello SuSE folkz, I'm looking for any (commercial or GPL) professional web development tools for Linux, which can resemble functionality of Macromedia Dreamweaver or Adobe GoLife. It's a very sad situation that professional web development tools exist mostly in Windows world. Could somebody tell me please if there is something for Linux? I'm not talking about Bluefish and Quanta. Thank you in advance. Alex
