At the risk of prying you away from the best DOS compiler in the world
(DJGPP) ...

Yes, Causeway supports .DLLs in DOS. And most Win32 .EXEs (PE)
produced by OpenWatcom can run under HXRT in pure DOS, even
with .DLLs. For instance, here's quoting from BINW's WLSYSTEM.LNK:

system begin cwdlls
    option osname=3D'CauseWay DLL (Stack parameter passing)'
    libpath %WATCOM%/lib386
    libpath %WATCOM%/lib386/dos
    op stub=3Dcwdstub.exe
    format os2 le dll ^
    libfile dllstrts.obj
end
system begin cwdllr
    option osname=3D'CauseWay DLL (Register parameter passing)'
    libpath %WATCOM%/lib386
    libpath %WATCOM%/lib386/dos
    op stub=3Dcwdstub.exe
    format os2 le dll ^
    libfile dllstrtr.obj
end

Keep in mind that I only suggest this since you're having such trouble
with Windows. Otherwise, DJGPP would be quite good enough (and has
better C++ support although OW18 has improved a lot). If I had a
Cygwin cross compiler for you, but alas ....

P.S. I think you have to use VDMSERV.EXE to debug DOS apps on Windows,
and even then, I'm fairly certain graphical stuff won't work. You'll
get more help for this on the following newsgroups:
