Another possibility is to install cygwin ( http://www.cygwin.com/ )
which will give you a rather goodly number of unix/gnu programs,
though they have the unfortunate habit of defaulting to bash, and
if you install a compiler and some basic build tools a nigh-unto
infinite number of programs become available.
That said, buying an older, cheap machine to install FreeBSD on
is probably the easiest. And who doesn't enjoy buying more stuff?

With PuTTY, you can connect to any unix/linux/bsd machine
with sshd enabled (though you need an account on that
machine to actually log in).

X forwarding onto a windows machine
( http://www.math.umn.edu/systems_guide/putty_xwin32.html )
may be best reserved for the 201 course.
