This might fit in the overkill category, but I went from knowing nothing about Catalyst to having a running DNS zone file editor in Catalyst, with differing user and admin access, in 7 days. This, while recovering from a hernia operation.

Catalyst is a stunningly fast development platform for a web app, and lends itself to combined CGI-web tools, by the nature of its design.

And to those who have advocated jQuery and jQuery UI, I lend a hearty ++ to that idea as well.
