After you ssh to host1, you will need to ether set DISPLAY. Or you
will need to use the -display option when you start the program.

export DISPLAY=:0

or

xterm -display :0 &

This will only work for when you are logged into host1 as the user
that is logged into X on that machine, or if you have disabled X
security on host1. (See the xhost command - it has to be run in X on
host1.)
