Yes, writing a program in your favourite language to output lines like
that shouldn't take too long.

It may be quicker to use a text editor to simply copy and paste and
then change some position values - I
use Gedit with the "Multi-edit" plugin which allows you to select
multiple lines and insert columns of
increasing or decreasing numbers, using just a few key strokes.

Copy and paste in PCB using the placement grid is also pretty quick -
select an 'S' shaped set of tracks,
copy, and then move your mouse and left click multiple times to place
copies.  Use the action :Report(NetLength)
to check the length when you're done.
