So much for resizability. What about color control of the button? I have
found by heavy experimentation that the color of the active dot can be set
by gtk_widget_modify_text and the color of the background behind the dot
by gtk_widget_modify_base. Is there any way to control the color of the
circular edge around it? Or is it always black, as I have seen?

I don't think you can change the size of the actual button, as this is
determined by the system you are running on. You could perhaps create
your own radio button widget and write custom drawing code for it.
