And here's some screenshots of Gtk2-Perl on Win32 made using the dropline Gtk2 binaries for Win32 (it has an installer) and the GTK-Wimp engine. Apparently binaries of Gtk2-Perl/Win32 are not currently distributed by the project, though they're planned.

Meanwhile Wayne Keenan does offer Gtk2-Perl binaries for Win32, but apparently did not build them against dropline Gtk2/Win32 (he includes instructions on what to install).
