I got an evaluation version of Qt for Windows and installed PyQt.
However, it gives me this error message:

It doesn't seem to see the "qt-mteval" DLL, even though I made

the PATH.

What you say is true. However, I didn't think the target audience of
this book was newbies. Python newbies yes, but not programming
newbies. For programming newbies I would recommend the "Learning
Python" book instead.
The availability argument, however, is a good point.
