PPAs is what launchpad calls apt repositories. It's possible to use launchpad to host apt repositories for Debian stable suites (testing/unstable would likely be more of a pain, but I haven't tried that) by specifying what suites to use when uploading. There are other SaaS hosts of apt repositories (e.g. packagecloud), or you can install one of the apt repository systems via apt on a VPS or similar, so if you have a deb built for Debian, there are options out there to distribute it.
