Best advice: go to a local statistician and ask for help.

Otherwise you must program the test. This means: you not only need good skills in statistics but also in programming. R (www.r-project.org) is a good prgramming language for such purposes, but - although it wil surely be beneficial in the long run - it will be hard to learn and require a lot of investment (time and nerves) - much much more than you will deem acceptable to solve just your current problem.
