Think about qemu like a nested computer, you can't access your host's
devices directly from guest, that's true for windows hosts, proof is you
can't access your real cdrom or hard drive within guest,right?. You have
to use files as guest devices.Everything you write on qemu hard disk is
written inside an only file on your host, the one you pass as -hd?. 
This way you can become familiar with linux or another OS, when you will
be confident enough (when you will run qemu as soon as windows started and
quit windows as soon as qemu shutdown), you'll find you don't need windows
anymore :)

IMHO, Qemu is a better way to learn linux powered OSes, the reason is
CoLinux don't use standard device like hd, but have his own devices and
drivers (AFAIK).

The best way to proceed is the one you understand most easily, there are
many way to do, if you feel dd for windows is perfect for your needs, just
use it, just make sure the tool you use produce image that qemu can read.
