If you really just want two windows (with no other windows), it's
particularly easy:

:sp | windo se scb crb

:sp[lit] splits the current buffer
'|' (<bar>) separates two commands
:windo does something over every window
:se[t] sets a variable in each of those windows
'scb' is short for 'scrollbind'
'crb' is short for 'cursorbind'

More info on each at:

:help :split
:help :bar
:help :windo
:help :set
:help 'scrollbind'
:help 'cursorbind'

For two arbitrary windows, with possibly many other windows open, it's
only slightly more complex, possibly with a better way to do it.

:se scb crb | sp | se crb

The second :se[t] command is necessary because the 'cursorbind' setting
isn't copied through the :sp[lit].

If you want vertical rather than horizontal splits, change the :sp[lit]
commands to :vs[plit]'s:

e.g.
:se scb crb | vs | se crb

:help :vsplit
