What is the most complicated thing the UI will do? Someone already recommended something that has charts? Do you need charts? This application sounds complicated enough from a business and backend perspective already, so why add to it by having a potentially complicated frontend? Render out your app with jquery and barebones html/css. Then decide if it just needs to be made to look better or truly needs more functionality. Don’t let anyone use any of the JavaScript frameworks (or set up a front end architecture yet), because then you’ll have another headache to deal with.
