Tk UIs will never be acceptably native as long as scrollbars remain a separate control from the thing being scrolled. This stops OSes deciding where the scrollbars should go based on input device and locale.
On OSX in particular, Tk UIs always stick out like a sore thumb for this reason, even with TTK.
I have looked at it but don't find examples that truly look convincing,and the info in the official page look very sad.

That's outdated and unofficial. Look at some examples with ttk.
Seriously. If you want a decent cross-platform UI system with minimal effort, which has bindings in just about every language, TK is really worth your time now.
