I should have said "stderr" rather than "stdout".
And the answer is:
from ctypes import *
from ctypes.util import find_library
libc = CDLL(find_library("c"))
libdialog = CDLL(find_library("dialog"))
class FILE(Structure): pass
libdialog.init_dialog(POINTER(FILE).in_dll(libc, "stdin"),
POINTER(FILE).in_dll(libc, "stderr"))
