I'm sorry, but from your current posts, I can see that you have no idea what you want nor how torrent trackers work.
You're asking for a "executable backend" for a torrent tracker. If you were even a bit informed about how they work, you'd see that MOST (or even all) of them are coded entirely in PHP. So the "executable backend" is a PHP script. PHP works both on windows and linux (lol). The torrent tracker scripts would work on any server having apache & php compiled with neccesery modules.
Get more informed on stuff you need before asking. Today everybody wants to do everything, everyone wants to own a hosting company, tons of websites, and doesn't want to learn anything. Things don't work that way.
EDIT:
NO, ITS NOT DEBIAN BASED. LOL
