Yes. Well, either you go Olivier's path (concoct an animated GIF with
all your images -- you can even embed timing info in that), or you start
with

  gdk_pixbuf_simple_anim_new()
  -- Creates a new, empty animation.

and add frame by frame with:

  gdk_pixbuf_simple_anim_add_frame()
  -- Adds a new frame to animation. 

In a timeout function (or possibly in an idle handler) you might have to
call gdk_pixbuf_animation_iter_advance() (I don't know if that's done
for you). The whole page

  <http://developer.gnome.org/doc/API/2.0/gdk-pixbuf/gdk-pixbuf-animation.html>

is worth a read.
