How to make JQM to an downloadable app

How to make JQM to an downloadable app

Hi, 

I am sure this must be one of those baby footstep questions.

Say I have am having an jQM + php + Db(JPD) built application fully functional.  As of now, there is no device specific features that this application is depending upon. If I type web URL it works in the smart phones. 

Now if I have to provide this as downloadable app is it possible and where should be the cut-off, I mean all processing are done at the server side. (basically nevertheless to say php generates the rendering JQM scripts). 

Should we keep building devices specific code say an Init screen or some sort and make that as downloadable app to the user and a button click internally calls up to our server side my JPD application. 

I have no idea on this, can you kindly guide the way to do it or look for some docs.

Please help me on this.
