You can call an external program, and have it make, for example, a png, and show that in a GtkImage/GnomeCanvas or whatever. Calling an external program can be done synchronously, using the C- function 'system', which is the easiest way to do it. More involved are the execxx series of function, but they permit more control over the communications. Gtk (more correctly, glib) has some functions to help executing external programs.
