title: Python GUI custom buttons
body: <p>I am looking to make a GUI in python but currently do not have much experience.  The GUI must have a few key features, namely a slider bar to control audio, and a few basic menu buttons. I realize essentially all GUI development tools could handle these simple features, but I am also interested in some custom content as well. The basic look of the GUI I am looking to create is shown here: </p>

  <p>In the image, the slider volume bar, "button1," "button2," the colored circles, and any slice of the circle (one highlighted section is shown) needs to be clickable and interactive. Moreover, the small colored circles must be able to dynamically revolve around the edge of the circle and remain clickable at all times. I have not used any GUI development tools yet, but have looked into pyGTK, pyQT, wxWidgets, and Kivy. Can anyone who has used these tools recommend which would be best suited? As far as shapes of buttons, am I restricted? </p>
