You might take a look at http://pdl.perl.org/.  I haven't used the
software myself, but have taken a close look.  Certainly less polished
than IDL, but there are so many resources to draw on from within Perl
(e.g. TK widgets, PGPLOT, compatibility with all kinds of file formats,
etc.), that things get interesting.  And if you're willing to get your
hands dirty there is an active developers group.
