Vaadin for Digital Signage

Hello,
I’m looking for a framework that allow me/us to create Page Designer App for a Digital Signage Product.
I need the possibility to provide to the user the functionality to create a new layout, drag/drop or add new media contents (like images, videos), move/place inside the layout where he wants and save/export the result as html5 page.
Is it possible with Vaadin Framework?
Thank you

Hi,
Vaadin is a java based frame work. so in order to auto generate the HTML5 based page out of the java / javascript based User Interface, you need to do some real programming.
