You can get GNU binutils for Windows here:

This sounds as if you want to debug the executable?  This is doable, but
without source code you will have to step through the assembler
instructions manually, or know where in the code to put breakpoints.  Use
your favourite Windows debugger, if you don't have one try gdb (part of the
full large Lazarus install I believe).  Even if this is what you want to
do, I suggest you dump the disassembled code into a text file, open this
and study it.  If the executable is stripped it may be very difficult to
make sense of the assembler code.
