I don't know of any software, but Lillefors's test is relatively simple, and described in many texts. Kolmogorov's test, which was the basis for Lillefors's, requires that you _completely_ specify the distribution (including mean and variance). Lillefors relaxed this requirement. If you have a spreadsheet with the Gaussian CDF available as a function, you can program it to perform this test easily. Good luck!
