Projectory is written in Perl...and, from the main page, "Projectory is an open source, platform-independent, web-enabled project management tool designed to track software projects through all phases of development."

If you want more of a workflow manager then you may want to check out RT.

On the off chance you want to put one together yourself, Gantry and Bigtop are pretty good web-app scaffolding that includes auto-CRUD.

HTH.
