Wascana is the name of the CDT for Windows project run by the excellent Doug Schaefer. It provides an installer with Eclipse, the compiler and loads of exras. The plan is to create a really good Windows desktop IDE.
Keep an eye on it over the next few weeks as it should be updating to GCC 4.2.1 and some form of wxWidgets support.
Certainly if it all comes together there is a powerful argument to use it instead of Visual Studio.
