Perl/Tk itself has no method calls for it, but you
can combine Win32::GUI and Perl/Tk. For an example look
at the "tkruler" application at 
http://ptktools.sourceforge.net

#!/usr/bin/perl
use warnings;
use strict;
use Gtk2::TrayIcon;

Gtk2->init;

my $icon= Gtk2::TrayIcon->new("test");
$icon->add( Gtk2::Label->new("test") );
$icon->show_all;

Gtk2->main;

Now Gtk2 and Tk mainloops can be made to work together, so that may give you an option. Basically, you make a Tk timer to update the Gtk2 loop every 10 millisecs. You can do the reverse too .... let a Gtk2 timer do a $mw->update every so often.

#!/usr/bin/perl -w
use strict;
use Gtk2;
use Tk;

my $mw = MainWindow->new(-title=>'Tk Window');

Gtk2->init;

my $window = Gtk2::Window->new('toplevel');
$window->set_title('Gtk2 Window');
my $glabel = Gtk2::Label->new("This is a  Gtk2 Label");
$window->add($glabel);
$window->show_all;

my $tktimer = $mw->repeat(10, sub{      
   Gtk2->main_iteration while Gtk2->events_pending;
  });

$mw->Button(-text=>'     Quit     ',
       -command => sub{exit}
        )->pack();

MainLoop;

I was going to try and test Gtk2::TrayIcon. I went to install the module and recieved this error:

  CPAN.pm: Going to build T/TS/TSCH/Gtk2-1.145.tar.gz

I believe that Gtk2 is installed since I have ran programs that used it before. Any ideas on how to fix this?

Perl/Gtk2 is based on the c Gtk2 libs, so you need to install the c libs before the Perl modules that interface to them. Your linux distribution may have the runtime Gtk2 (Gnome libs) as a separate package, with the "devel libs" in another rpm (or whatever). SO if you can run Gtk2 programs, but can't compile them, install the "gtk2-gnome devel" package.

If that is not possible, get the c libs yourself See Perl/Gtk2 Faq

The basic libs are only needed, not the entire Gnome library set. They must be installed in a certain order

pkgconfig
cairo
glib
pango
atk
gtk2
[download]

You usually have to keep the same pkgconfig location.... defaults to /usr/local, but it's easiest to keep them in /usr, so when you configure them, do

./configure --prefix=/usr
[download]

Get the latest versions from Gtk+ downloads then install in the order above, then install the Perl modules in the same order.
