I am happy to let you know that finally the unofficial Portable Strawberry Perl (beta 1) with Padre 0.25 is available for download.
This is based on the Portable Strawberry Perl (beta 1) release by Alias and this is just a hack, but it works.
Not only that, but it also includes a development version of Parrot and Rakudo along with the Perl6 plugin of Padre. So not only can you use Padre from this download but you can also write, syntax highlight and run Perl 6 code right from Padre.
It isn't small, 60 Mb download, 300 Mb unzipped but it is worth it!
