jQuery Mobile. And then?

jQuery Mobile. And then?

Hello,
I'm Italian and I speak little English ..
Anyway .. I'm just ushering the mobile programming and I started studying jQuery Mobile.
Now I doubt arises: how to use Dreamweaver HTML editor and jQuery Mobile as a framework for the graphics (buttons, lists, etc ..), but what language should I use to effectively control the hardware of a smartphone? For example, to activate the camera, gps, etc ..?
Thank you
Max
