How to create a WIdget-BACKOFFICE with dynamic behavior similary a JSP

We are trying to incorporate a widget in BackOffice where the user going to select an option from a HTML-SELECT representing a different report, in base at the option this going to show a form with input parameter´s for the report, this is a dynamic behavior similary a JSP, using javascript or jquery and ajax request. The query necessary for this report is described below: Is possible integrate this requirement in BackOffice ?
