I am looking for a data entry forms framework.  Rather than create a new app every time a customer group wants to have a simple CRUD form to a database, this should be something that is built simply by configuration to a reusable app.  Is anyone aware of any such tool?  I'd like something with a pleasant user experience fitting with today's modern UI styles rather than plain and empty but I'd settle for plain and empty; I just don't want to keep writing new CRUD apps every time I turn around.

thanks for any suggestions.
