I just had a he** of a time doing the same thing.  For some good info read
the FAQ and also the answers to my post  dated 9/27 at 10:56 pm.  The most
important thing is to make sure you know how to use your compiler!! It is
very different from one to the next,  I use Borland if  you need help just
email (as it's off topic here).  In general though,  you'll need 3 files one
header.h that has just the struct defs, function prototypes (with a
semicolon on the end) and any macros you want to put in there.  the 2nd file
will be header.c this file will #include the header.h file (in quotes " ",
not < >) you just created and it will contain all of the code for the
functions in the .h file.  Compile the header.c file.  The third file you
need is yur actual program that will create your .exe file.  in this file be
sure to #include the .h file.  Compile it and enjoy - hopefully.
Like I said a lot of it is compiler dependent  <off topic> how you set up
your project and structure the nodes that you add to it </off topic>.  Good
luck
