WebPermutation tests can be used to create confidence intervals, but it requires many more assumptions, that may or may not be reasonable (so other methods are preferred). The Mann-Whitney/Wilcoxon test is actually a special case of a permutation test, so they are much more popular than some realize. WebPermutation procedures are available for a variety of tests, as described below. For some tests, however, these procedures are not available (e.g. SNP x SNP epistasis tests).
