There are a couple of scaffolding tools for asp.net mvc but I don't think none of them can be compared with Grails scaffolding capabilities: http://www.grails.org/Scaffolding

Subsonic has this feature for web apps, but I don't believe it has this feature for WinForms apps.

Subsonic is open source and based on T4 templates, so it's very possible that you could modify the Subsonic T4 templates that generate the WebForms scaffolding and have them generate WinForms scaffolding instead.
