The routine zipconv.bat is freeware (http://w-shadow.com/blog/2009/01/29/...so-etc-to-zip/

There's really no need for an external library. Given the existence of the ZIP and EPUB output plugins, adding support for CBZ to Calibre should be trivial. I suggest you put in a request to add a Calibre Output Plugin for the CBZ format.
This might be a good starting point:
