Create GUI application from XML description - Linux

I need a simple piece of software that reads an XML file that describes a GUI screen and translates it into a working GUI screen. For example, something like: Should create a screen with a tab control holding 2 tabs, each tab holds the respective input fields. The XML describes the location on the screen, e.g. and design info such as colors/font etc. The XML also describes JavaScripts actions such as onBlur=validateInput() so the software should include a JavaScript interpreter. The application should supports grid/table based presentation of data or pre-populating input fields from data received as in a data XML format. The XML files (both the screen description and the data) can be local or received from a remote server using a standard HTTP request. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
