Yes. The hard part was figuring out (a) what to download, and (b) how to 
set up the environment so the compiler and linker could find everything 
they needed.

 From my rough notes:

Download and install Visual C++ Toolkit, Platform SDK, and .NET 
Framework. One of these also had a prerequisite that required 
installing. Don't remember what it was, but it was obvious.

Look for .bat files that set up path and environment variables in the 
installed directories and execute them. The files I needed were called 
SetEnv.bat, vcvars32.bat, and sdkvars.bat. I'll try to write up the full 
paths tonight.

Append the necessary paths to %INCLUDE% and %LIB% to find headers and 
libraries for your extension.

With all that set up, the standard idiom using extconf.rb worked fine.
