I'd add Darktable (www.dartable.org) to the list. It's awesome although 
it's not available for windows, just Linux and OSX.

The aforementioned programs are specialized tools for RAW processing and 
can be used in conjunction with GIMP, pretty much like Adobe Photoshop 
uses Adobe Camera Raw as a gateway instead of offering tools for 
processing RAW directly in Photoshop.
