I had some time today, so I figured it out myself. Here's an abbreviated description of what I did, should someone else ever want/need to do this:
1) Using Disk Utility, I created a new blank disk image, specifying a format of MS-DOS (FAT) and 128-bit AES encryption.
2) After creating the image, I then mounted it using the password I specified at the time the image was created.
3) I then went to the Sharing area of System Preferences, turned on File Sharing, and in the Shared Folders area, I added the mounted disk image as a new folder. I then set up appropriate user access permissions.
4) Clicking the "Options..." button in the Sharing area of System Preferences, I checked "Share files and folders using SMB", and enabled my user account for access.
After setting this up, I was then able to access my Mac from Windows Explorer on my Windows XP machine (the Mac required authentication on the Windows machine prior to granting access to files). Once I had been authenticated, I was able to read and write to the OS X encrypted disk image from my Windows machine. Keep in mind that Windows is not able to actually open the encrypted image; I had to mount the image on the Mac before Windows could access it. But this is exactly what I needed. Sensitive files can be securely maintained on my Mac, but easily be made accessible to Windows-only software.
Feel free to reply if you want additional details about setting this up.
