You can look at that example by Zack Rusin, it is very simple, here is code:
http://ktown.kde.org/~zrusin/examples/argb.tar.bz2 (look at main.cpp)
That Display instance come directly from xlib, it is created by XOpenDisplay:
http://lxr.freedesktop.org/ident?i=XOpenDisplay
In Python, I am using ctypes module to directly access xlib (libX11)
and call XOpenDisplay.

I meant, in the context of PyQt. PyQt needs to know about the type.

I can't help you much in this, I don't know much about ctypes, I have only learned it
because I want to create ARGB windows with PyQt (and then I realized that I
can't do it
because PyQt doesn't support it). But you can try this code:
### Python code ###
import ctypes
class Display(ctypes.Structure):
pass
xlib = ctypes.CDLL('libX11.so.6')
xlib.XOpenDisplay.restype = ctypes.POINTER(Display)
xlib.XOpenDisplay.argtypes = [ctypes.c_char_p]
display = xlib.XOpenDisplay(':0.0')
### End of Python code ###
This will create 'display' object, which is pointer to 'Display' structure
(which is derived from standard ctypes.Structure).
But this is all I can tell you, as I said I don't know any details about this
process, only that it works (I have tried creating window with pure xlib).
Ctypes are standard module in python 2.5 (for Python 2.4 it is external
module), so I think PyQt should support it.
The ctypes extension doesn't build on AIX, HP-UX, IRIX and Solaris. With
some changes, it may build on IRIX and Solaris, because libffi has been
ported to these platforms. On AIX and HP-UX, you have definitely lost.
I've never understood, why ctypes became a standard module.
PyQt works on the above platforms. Making it dependent on the ctypes
extension seems to be a bad idea.
