Jeff,

The answer is yes, using MathLink.  MathLink provides a tool (called
mprep)  that allows you to call functions written in C/C++.  You could
use mprep to create an executable that is linked to your dll.  You
could either call functions in your dll directly, or write C wrapper
functions for your dll functions.

I would recommend looking at the MathLink documentation in the
Mathematica Book, and compiling the addtwo example in the MathLink
Developer's Guide.  Addtwo is a simple example of calling a function
written in C, from Mathematica.
