I've been using WxPython and I've tried Tk, but it seems that, while both are good and I'll likely use them for other projects, neither of those appear to be capable of accomplishing the things that I want for my current project (which is fine, they're good at what they do).
Basically what I'm looking for is something that will allow me to make rich graphical GUIs. My specific goal is a window that will draw bitmap buttons, resize the parent window automatically to fit them, and possibly animate the resize with a slide effect and have the buttons fade in. Also being able to have my own window border style instead of the inbuilt one is important to me.
This particular project will be Windows only, so non-portable libraries are fine in this case, though portable ones would be great too.
If I missed how this can be done in either WxPython or Tk, I'm all ears.
