I think this is a mistake. For one, you are binding them to Microsoft servitude and this will cause them to think less. Part of Perl (though we do have Win32 support) comes from the Unix culture. A ton of it. Perl initially was (and still is) a blend of sed, awk, and lots of Unix tools. The power of Perl would not have arisen if it's birthplace was Win32.
Also, how many programmers avoid Linux because they are bound to VC++? It's scary. VC++ is an overglorified text editor once you know how to write makefiles -- makefiles are easy -- everyone needs to know them who does C/C++.
Show them to ActiveState.com -- tell them the compiler is free and encourage them to download it. They will love free tools, free documentation, etc, etc. They can still use MSVC as an editor, or something free like Crimson Editor instead!
