Mac applications are actually folders on a file system level with the suffix '.app', inside which any resources, icons and executable machine code is held. As Windows doesn't use this convention, it just sees them as normal folders which you can browse as you would any others (you can see inside applications on a Mac too, by right clicking the application icon and selecting Show Package Contents).
Therefore, to distribute the application, simply zip the battlespace.app folder and it's contents, and upload it to your webserver. Mac users who will download it, will simply see your application inside the ZIP.
