I can imagine a little CGI HTML/CSS page which would make this a more visual process.

Show the pattern, and show the sample string. For each token in the regex, or just for each grouping set of parens, wrap both the regex and the subsequent sample string with <span style=...> tags that set the background colors for each range.
