You get the labels in the correct order. pack_start and pack_end
are filling the box from the beginning and from the end:
START END
pack_start(label1):
START label1 END
pack_end(label2):
START label1 label2 END
pack_start(label3):
START label1 label3 label2 END
pack_end(label4):
START label1 label3 label4 label2 END
You should read the chapter about boxes in the gtk tutorial.
