A lot of those issues would be "back end framework" issues if we had a decent GUI markup standard. Tk would just be a kit to build a GUI browser with, not the domain application itself. It would be roughly analogous to "WebKit" in HTML-land. When building a domain application, you don't normally set out to build a domain application "in" WebKit, you use HTML/HTTP/CSS/JS, which are then rendered via WebKit (at least partially). A web browser doesn't have to use WebKit.
