You want this as HTML app, do you?
It sounds very straight forward to write a simple script using the CGI module which overs a simple HTML form, gets the content and put it in a standard HTML container inside <pre> tags.
As unique identify a checksum could be used (->CPAN) and then you need a simple main HTML file holding a list/table of links to all entries.

Could be done with 100 lines of code. Just in case you don't find a module for it.
