Yes, it is possible, and doesn't even require a command-line switch to do.  All
you need to do is create a Library Definition File (*.def).  Here's an example:

================= Begin test.def ================= // Do not include this line
LIBRARY         TEST
DESCRIPTION     'An Example DLL'

EXETYPE		NT
CODE            PRELOAD DISCARDABLE
DATA            PRELOAD SINGLE

EXPORTS
testfunction  2
anotherfunction   3
================= End test.def ================= // Do not include this line

Your methods need to be marked as extern as well as listed in the definition
file.  If you want to see a working example, check out
http://www.scratch-ware.net/d/ to see the Python/D DLL example at the bottom.


You can also look at the D for Win32 link:

http://www.digitalmars.com/d/windows.html

and scroll down to DLL (Dynamic Link Libraries) for a rundown including this
link:

http://www.digitalmars.com/ctg/ctgDefFiles.html

which describes in detail how to construct a .def file


Hope this helps

An example of creating a DLL in Windows is here:
http://spottedtiger.tripod.com/D_Language/D_Hub_Adv_Tutor_XP.html

It shows how to create a DLL.
Then copy the DLL into C:\dmd\MKoD_ex\WinDLL.dll
Then it shows how to create a file that uses the DLL. Great stuff.
