Of course, you can use Gdk::Window#set_back_pixmap(), but you need some
special implementations because it's a row-level API.
e.g.) you need to get expose event yourself and clear area where you expose.

If you want to set background images, I recommand to use Gtk::Style instead.

------
require 'gtk2'

Gtk.init

win = Gtk::Window.new

win.signal_connect('delete-event') do
   Gtk.main_quit
end

pixbuf = Gdk::Pixbuf.new("logo.png")
pixmap, mask = pixbuf.render_pixmap_and_mask

win.add(Gtk::Button.new("Test"))
win.set_default_size(200, 200)
win.border_width = 50
win.border_width = 50

style = Gtk::Style.new

# You need to set the Gtk::StateType as you like.
style.set_bg_pixmap(Gtk::STATE_NORMAL, pixmap)
style.set_bg_pixmap(Gtk::STATE_ACTIVE, pixmap)
style.set_bg_pixmap(Gtk::STATE_INSENSITIVE, pixmap)
style.set_bg_pixmap(Gtk::STATE_PRELIGHT, pixmap)
style.set_bg_pixmap(Gtk::STATE_SELECTED, pixmap)

win.style = style

win.show_all

Gtk.main
