What I described is all I've done firsthand.  But more is possible.  And 
I've worked on fancier setups, but somebody else did the plumbing.

As Stephen points out, you can use webbrowser module to launch a 
browser.  So you could write python code to create a web page(s), write 
it to a file, then launch the browser using the "file://......" 
protocol.  That'd be fine for displaying pages that are generated 
entirely before launching the browser.  But if you want the python 
program to get feedback from the browser (which is usually what's meant 
by using the browser for a GUI), you're going to have to simulate a 

That can be done on a single machine using the "localhost" shortcut.  I 
don't know how to do it, but there is a sample in the 2.6 release of 
Python, at least in the Windows version.  You run it from the Start 
menu->Python2.6->module docs.

The source for the main server is in 
c:\Python26\Tools\Scripts\pydocgui.pyw.  (though all it does is import and call it.)  Now that particular program's purpose is to 
generate and display docs for the python files on the system, but 
presumably it's a starting place.

Now, this is the first I've looked at this file, but at line 1967 is a 
function serve(), which is commented as the web browser interface.   The 
function serve()  probably has much of what you're interested.  In 
particular, it contains a few class definitions, including DocServer and 
DocHandler, which send data back and forth to the browser, over the 
localhost connection.

It looks like it gets its core code from BaseHTTPServer module.

At line 2058 is a function gui(), which is a small tkinter program that 
just displays a few buttons and such.  That's not what you're asking about.

Hopefully somebody else has actually used some of this stuff, and can
