This is not an announcement, but a suggestion.
If anyone with experience in both MFC and wxWidgets came up with such a plugin would prove extremely useful for adoption of wxWidgets. A lot of MFC programming work is about to die, with the advent of .NET, and coming Windows Vista, and recovering such work with a plugin which automates a great deal of tasks would prove helpful and motivate further use of both wxWidgets as well as Code::Blocks.
Unfortunatley, I am busy ATM, and also have no solid knowledge of MFC.
