I don't believe its possible in Chrome, starting an EXE on a users computer could be considered a security violation. Some ActiveX, and file:// links in internet explorer may work. Also, OneClick deployment may do something similar to what you are after (not exactly though I don't think, and I believe they require an add-in which may not be available for Crhome) http://www.15seconds.com/issue/041229.htm

I'm not sure what you're asking for. You can start an application on your computer just by linking to it in the HTML page. However, if you need to pass data to it, then it's a different matter altogether, although it's still simple.
An example is what www.nexon.com does with it's MMORPG, MapleStory. You log on to the website, and the web page starts the game after the authentication. Another example would be the magnet links on file-sharing sites.
You need to create a protocol handler, it can be in any language like C++/C# and register it on the client's computer. Like so - http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx
Then, just use the protocol you built to pass on whatever data necessary. You can add a link that can be clicked, a button, Response.Redirect() from the server, whatever you like.
