There is a command line utility for converting an image to a string

gdk-pixbuf-csource --raw someimage.png > someimage.h

You can then #include this into your program
i.e.

#include "someimage.h"

GdkPixbuf* pixbuf;

pixbuf = gdk_pixbuf_new_from_inline (-1, definedimage, FALSE, NULL);   
<-- look in the #include file for what 'definedimage' is really called; 
I forget.
g_assert(pixbuf != NULL);

gtk_image_new_from_pixbuf (pixbuf);
