I would do it like so:

----------------------------
qemu-img create dos.img 10M
----------------------------

Then, you can boot the qemu image with your floppy drive specified as 
follows:

------------------------------------------------
qemu -hda /path/to/dos.img -fda /dev/fd0 -boot a
------------------------------------------------

qemu will boot from the floppy with your dos.img as the HD (future c:\ ). 
Then run fdisk from the Chinese DOS floppies to create an active DOS 
partition on the qemu disk image and to format it.  After you've done that 
you can sys the new qemu c:\ and copy all files from the floppies to it. 
You can also put your WP floppies into the floppy drive and copy files 
from them over to the new qemu c:\ .  You'll need to virtually remove and 
insert the floppies via qemu monitor (ctrl-alt-2--issue "help" there for a 
list of valid commands, ctrl-alt-1 takes you back to the running qemu 
image).  You should be able to reboot without the -fda switch and go 
straight into the new DOS running from your qemu image.  It will 
undoubtedly take some experimentation to figure out all this.

PS  You can apparently use dd to create your qemu hard drive images too, 
but since I've not done that I'll let others describe how that would work. 
I prefer to use qemu-img (probably a script that calls dd?).
