It is possible:
import sys, gtk
def delete_event(win, event=None):
gtk.main_quit()
def do_display(pixbuf, name) :
win = gtk.Window()
win.connect("delete_event", delete_event)
win.set_title(name)
box = gtk.VBox()
win.add(box)
swin = gtk.ScrolledWindow()
box.pack_start(swin, gtk.TRUE, gtk.TRUE, 0)
image = gtk.Image()
image.set_from_pixbuf(pixbuf)
swin.add_with_viewport(image)
win.set_default_size(600,480)
win.show_all()
fname = sys.argv[1]
pixbuf = gtk.gdk.pixbuf_new_from_file(fname)
do_display(pixbuf, fname)
gtk.main()

Though a little longer the code above has the advantage of only
using plain Gtk, which makes it work under windoze as well :-)
