In brief, Perl Composer is a UNIX version of Visual Basic. It is designed to simplify the creation of GUI front-end of UNIX programs.
You can get it from http://linux.ece.uci.edu/~wangy/PerlComposer/download.html.
It's still in the design phase. The current version is just a proof of concept, and cannot presently be used to create any reasonable projects.
