Yeah, me too. :)

This one really has me squirming in my seat. C++ isn't a very good language
for learning just a little bit of. Compared to Python I would say the
learning curve is much steeper. It offers a lot of control over how the
object code is generated but that also makes it dangerous for casual users.
If you do it wrong a lot of bad things can happen, including poor
performance -- although poor performance would perhaps be the best of those
I suggest you look at various Python libraries to do whatever numerical
processing you might need to do. They are mostly written in C anyway so
their performance is excellent. For instance, I use SciPy for Fourier
analysis and PIL for image processing, getting good performance on these
numerically intensive tasks without ever leaving the ease and comfort of
good old Python.

I wouldn't choose your C++ compiler for Python compatibility. How good is
the debugger? How is the standards conformance? C++ compilers vary widely in
these and other important criteria.

Take a look at the UVS library under my sig for some C++ code which I have
found useful for statistical simulations.

The .NET compiler has a very good debugger and much better standard
compliance than the old 6.0 compiler, but I haven't used lot of different
recent vintage C++ compilers.
I would also like to make .dll files that I can plug into

I generally use COM objects written in Python to connect to Excel. I am very
pleased with that technique.
