Hi Sonu,
You can use any template other than plugin project and kapsel. All other templates gives you a web application that runs on PC and mobile browsers. But if you want a hybrid mobile app you have to go with kapsel, ex. to add a functionality to access native features of phone like camera.
Plugin project template is used to add a new functionality to your Web IDE itself - http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e08212a2-fa1f-3210-849e-937b08a82071?QuickLink=index&…
