It is true that you do not need to modify Apache's main httpd.conf file; 
however you still need to create aliases.  See the instructions in 
/ms4w/httpd.d/README_HTTPD.txt (you will notice that this is how all of 
the MS4W add-on packages function).  Again, the best way to learn is to 
download another MS4W add-on package and look at its structure.
