Question: How can I get the Studentized Range (q) distribution used in Tukey's post-hoc HSD test?

With Statistics, how can I get/compute the Studentized Range distribution, commonly called the q distribution, which is used in Tukey's post-hoc Honestly Significant Difference (HSD) test (Wikipedia link)? Does this distribution exist in Statistics with a different name? Can I calculate it as some combination of distributions that do exist in Statistics? I know that it is closely related to Student's t distribution.
