Not true.
see
http://www.imagemagick.org/script/binary-releases.php
"You can install ImageMagick from source. However, if don't have a
proper development environment or if you're anxious to get started,
download a ready-to-run Unix or Windows executable."

Learning python would be easier.

I like to use the GIMP Python Console for batch processing.
Here is an example, that processes all PNG files in the current directory.

import glob.glob
for filename in glob.glob ('*.png'):
image = pdb.gimp_file_load (filename, filename)
# put your batch processing commands here.
# for example
#
# pdb.gimp_threshold (image.layers[-1], 128,255)
# would threshold the bottom layer.
#
pdb.gimp_file_save (image, image.active_layer, filename, filename)
del image
