What you basically need on Windows is RTools. See the following link 
for step-by-step instructions:

Once you have set this up, you can write down your ODE as raw C code as 
described in the vignette. You might also have a look at the cOde 
package which does the C code generation for you in an automated way.

Sorry, I cannot comment on this.
