Nativefier is based on the Node.js runtime, but it goes a few steps further, allowing for quick and automated conversions from regular old web sites to stand-alone desktop applications. You could right now make this site into a piece of software. In fact, I just did.
Nativefier is plenty user-friendly: it runs from the Node.js command line simply as "nativefier 'somewebsite.com'." (There are some additional options that can be specified, but that's all explained in Nativefier's brief documentation.) World, meet PornHub.exe.
