You generally don't develop for a single distro: you develop for linux. Which then works on every distro. If you're optimistic enough you could even try to make it work for every *nix, but whatever.

The only reason steam is made specifically for ubuntu is because it uses apt-get to actually get steam. If valve put more effort into making it like every other linux application nobody on any distro would have trouble running it.
