Looking for a very specific type of embedded GUI kit

[Sizer]

We make embedded devices that are basically wimpy linux boxes with small 
custom display/touchscreen heads on them. They're not running X or any 
other windowing system. All development is done with C++ and PEG 
(Portable Embedded GUI) driving the display. PEG lets you install your 
own hardware driver to talk any custom hardware, which is what we've 
done.

Currently we have an upgrade/installer application that boots from CD, 
reads an XML manifest, does what it takes to reformat the drive, 
partition it, install the correct packages, etc. etc. All the while 
displaying on the little screen what it's doing so there's some obvious 
progress going on. 

Doing this kind of thing in C++ is very painful, so I've suggested that 
perhaps the installer could be done in Python - at which point we have 
the issue of which non-X graphics toolkit we can use. If this works out, 
we'd probably like to replace other C++ tools with Python as well.

So the question is: what non-X gui toolkit can we use that has Python 
bindings and will let us use a custom display driver at the lowest level?  
Qt/Embedded looks nice, but I don't see anything about Python binding 
(though as I write this I've found PyQt). I've also looked at nano-x and 
picogui from doing google searches on the newsgroup. Can wxPython run 
without X? I don't think so, but could be wrong. Should we just write our 
own python wrapper for PEG? I'm still researching, but figured I'd ask 
here in case anyone had any relevant experience and could point me 
somewhere.
