In addition to the above answers, I would like to say about using Perl in web applications. I've installed and configured Apache 2 with mod_perl 2 (I have got Perl 5.8 on my computer) and Mason but I cannot install Embperl 2 because module for ActivePerl is not exist and doesn't compile under win32, Apache 2 and mod_perl 2. Also, I've had problem with Net::Pcap, but I've found Net::Pcap and Net::PcapUtils in the repository one guy (see here, if you are interested).
But, in general, Perl works under win32 without big problems.
I would like to suggest you IDE for Perl:

• HTMLKIT - very usefull IDE (supports Perl, Java, PHP, HTML etc.). You can configure it easy for run Perl script.
• AbsolutePerl - very power Perl IDE, but it has Russian interface (unfortunately :-((( )
