Re^2: How do you make Tk look good?
in thread How do you make Tk look good?
So, what did he say? If he just didn't respond I don't think you can draw any conclusions about how hard it is. (UPDATE: whoops, I see now that you had this in your original post!)
I don't see how you can give up on something you obviously want quite badly without even trying... You might learn something even if you're ultimately not successful. Since the author is already planning to integrate Tile in the future you could ask him how he plans to do it.
