Portable FLOSS Successor to FrontPage / Dreamweaver?

FrontPage / Dreamweaver provided a bunch of features and utilities that made it very easy to quickly code a static or dynamic website.

Although many use plain text editors now, some of you out there might still be fond of a WYSIWYG GUI experience.

I'm familiar with Komposer and BlueGriffon, but I tried using them (I only used the Windows portable versions) and both either froze on me (at some point) or had errors pop-up.

What are some portable (Windows) FLOSS successors to FrontPage / Dreamweaver that you use?
