I would like to suggest you HTMLKit. This is a 'full-featured editor designed to help HTML, XHTML and XML authors to create, edit, format, validate, preview and publish web pages, scripts and over dozen other file types', free and supports Perl, Embperl, PHP, Java, JavaScript, HTML, XML etc.
HTMLKit has many plugins for expansion its functionality.
For tuning this editor for Perl development try to install follow plugins:

• dwPerl - adds a possibility to run and debug your Perl script, a commonly used code snippets and drop-down list with all functions of your module of script for quick jumping to the function definition.
• hkPerl - adds a list of related Perl functions which can be used for help and quick insert.
• Perl Reference - adds a keyword help file for Perl 5 functions (online and offline versions)
• avwHTMLTemplate - inserts commands and control structures used by the HTML::Template Perl module
• Plugins Generator - adds a possibility to visually design plugins which will consist your information (for example, I've created plugin which consists a library of HTML controls, generated using Embperl).

Also, you can install Vim for Windows and configure it for Perl development as TVSET suggests in his post Vim for Perl developers.

In my mind, Vim is the most power, flexible and useful editor and it permits me be at easy at developent under any operation system. Many scripts permit you to configure Vim for your needs and tips help you to use Vim more efficient.

I hope that this post will help you to choose a good for you Perl IDE.
