OK .. such thing you will have to code yourself. I don't think you will find it anywhere.
1) You will need a server-side script (PHP, ASP.NET, JAVA/JSP or similar language that can connect to MySQL and be controlled with HTTP-requests) that should be uploaded to the server.
2) The binary on the client machine will have to communicate with that script.
The SQLyog tunneler cannot be used as a 'generic proxy' for other programs. Only the SQLyog binary can communicate with it.
