[Qgis-developer] Which environement for Windows XP devt?

[Henri De Feraudy]

Hello,
  I was a C programmer for many years, but havent done any for 10 years.
  I did dabble in C++, but never developped anything serious. 
  I did work seriously on C# for two years, quite recently.

  I'm back into some development (on QGis) and have no experience with Qt or any other development environment in Windows other than Visual Studio.

Now I want to develop with FOSS tools. Which C compiler would you recommend I get? Should I develop with MinGW or CygWin? Can I have both installed on the same machine.
Thankyou 
Henri
