Looks like more than one step....
I use Bluefish (not a WYSIWYG like Dreamweaver). There is also Nvu
You might check if Dreamweaver works with WINE/CrossOver. (For CrossOver, go to Codeweavers' site.)
3) You can most likely run it with wine
I would not go quite so far. WINE will not run everything and nor will CrossOver (the commercial version of WINE)
Depending on your needs, you may want to keep windows in a dual-boot setup or running on a Virtual Machine (VM) such as Qemu, Xen, or VMWare
