Microcal Software's Origin is probably what you are looking for. It has a
large number of pre-defined fitting functions. You can also enter your own
fitting functions without much problem, although it is rather slow. The
latest version that I have used is 4.0. It is a 16-bit Windows program and
runs comfortably on a dx2-66 with 8mb. A 32-bit version is due out soon, this
may improve the speed of the user-defined fitting functions. They probably
have a web site, but here is the Letter Head:
