You should be able to run WfWG on DOS without QEMM.  If you are running DOS 
6.0 or later, use the HIMEM.SYS and EMM386.EXE files from \DOS.  If you are 
running DOS 5.0 or earlier, use the HIMEM.SYS and EMM386.EXE files from 
\WINDOWS.  The basic rule is to use the newest files, but some OEMs change 
the timestamp on the files as they please.  Correcting this ought to solve 
80% of your problems.
If your issue is that QEMM simply gives you more UMB space than EMM386, you 
can usually improve the performance of EMM386 through two or three simple 
tricks.  First, if you have network cards with memory apertures, such as 3Com 
or SMC, then you need to move the aperture to the lowest address possible 
above the video ROM, usually C800.  Pushing the aperture to one side like 
this provides the largest contiguous UMB area.
Second, do not enable EMS through EMM386 unless you actually need it.  That 
is, use the "NOEMS" switch instead of the "RAM" switch.  Eliminating EMS will 
save you a 64 KB page frame in the UMB area, which can now be used to load 
drivers.  While QEMM can use "Stealth" and other techniques to do both, 
EMM386 is less sophisticated.  If you must have EMS and therefore a page 
frame, also force this to the lowest address possible, usually D000 (right 
after the network card aperture) or C800 (for NE-2000 or other network cards 
without a memory aperture), in order to preserve the largest contiguous UMB 
area.
Third, if you have fairly standard BIOS machines, you can usually safely use 
the "HIGHSCAN" switch on EMM386.  If this does not work, your machine will 
lock up hard on boot, and you can remove the switch.  Despite the fact that 
it works on 90% of modern motherboards, Microsoft never automatically enables 
this feature because it would create technical support nightmares for less 
experienced users who discover they can no longer boot.
