This is fairly easily done with MathLink and a C compiler.  Try compiling 
the sample MathLink program "addtwo" following the instructions in the 
online help for the MathLink Developer's Kit (Add-ons->MathLink 
Library->System-Specific Information in the help browser).  Once you get 
that program successfully compiled and running, it is a fairly simple task 
to change the "addtwo" function to call a function in your DLL, and change 
the project or make file to link in the .lib file referencing that DLL.

Incidentally...I think the documentation may be a bit unclear on where the 
sources for the sample programs are.  You can find them in...

<install directory>\AddOns\MathLink\DevelopersKits\Windows\MathLinkExamples
