GUI programming in Perl typically involves the use of the Tk module, which is a toolkit for creating graphical user interfaces that can be used in Perl.

Here is a simple example code demonstrating how to create a basic GUI window in Perl.

use Tk;

my $mw = MainWindow->new;
$mw->title("Hello, GUI!");

my $label = $mw->Label(-text => "Hello, Perl GUI!")->pack;

my $button = $mw->Button(-text => "Click me", -command => \&button_click)->pack;

sub button_click {
    $label->configure(-text => "Button clicked!");
}

MainLoop;

The code above creates a simple GUI window with a label and a button. When the button is clicked, the content of the label will be changed.

It is important to note that the Tk module requires the Tk toolkit to be installed on the system, which can be done through CPAN. Additionally, there are other GUI toolkits available for Perl, such as WxPerl and Gtk2-Perl.
