Cairo likely doesn't provide the right abstraction for coloring a pixel on the screen, since its focus is on drawing vector shapes.
Similarly, Tk forces interaction with the library to be through strings, which is highly inefficient for passing in large chunks of data. Although if you only want to draw colors, and none of the other widgets that a toolkit provides, you might consider using one of the OpenGL bindings in Julia.
