Hi jason,

I don't know offhand if there's already something which exists to do that.  I did a (not-at-all comprehensive) search for it myself, and couldn't find anything relevant.

But, have you looked at P4Perl at all?

According to the documentation:

[P4Perl is] a Perl module that allows you to execute Perforce commands
without leaving Perl space and to get the results in Perl Arrays and H
+ashes.

It seems to me like you could combine that with Perl/Tk fairly easily, although you would have to write the Tk part of it yourself.
