What are some solutions for distributing an HTML5 based desktop application?
I want to be able to distribute my HTML5 app as a standalone desktop application on Windows, OSX, and Linux. I would like for people to be able to double click my app icon shortcut to run my program.
I don't want the browser window showing at all, just my app. Is this possible?
HTML5 Apps in 2014
Frames by chrome/webkit
Electron (former Atom Shell)
The folks at github use this to provide their code editor Atom as an app. It has an documented api and a help channel on the official atom forums.
Node-Webkit, the most minimal approach
Intel is behind this (?). I've been told it's very rough around the edges.
Brackets Shell, the sandbox of Adobes code editor (and base of Adobe Edge)
says the readme, but there are quite a lot of folks out there who did it nevertheless.
Frameworks + Tools
Adobe AIR, as another answers suggested.
Sencha is a company which sells tools for app developers, including html5 app development and distribution.

Tide SDK (archived on 2015-07-12 at archive.org), beta version, discontinued on 12th Jul 2015
XULRunner from Mozilla may do the trick for you but adds some overhead.
app.js ended at 28th Oct 2013 for being surpassed by (https://github.com/rogerwang/node-webkit)[node-webkit].
Mozilla Prism is decomissioned, their slugline was:
Check this new project from Mozilla. You can create desktop apps too : https://developer.mozilla.org/en/Apps

Currently the answer is that are different solutions of each platform.
You can try Phonegap, there is a Windows Desktop Port: https://github.com/davejohnson/phonegap-windows
I tried the mac-port, it worked well. I didn't try the windows version yet.
You might want to look at XULRunner from Mozilla. At a 10000 foot level, the FireFox browser is a XULRunner application (obviously a very sophisticated one, but...). But XULRunner lets you use Javascript and XML to create applications, and the browser window is one of those components, so you once you get your basic window up, you can likely do pretty much anything you want.
Also, depending on the sophistication of your application, there are several "widget" frameworks (like Dashboard on the Mac, Yahoo Widgets, Windows Gadgets) which are basically HTML runtimes as well.
