You can use gksudo to launch xterm.

[rocketmouse at archlinux ~]$ gksudo xterm

Does open xterm with a root prompt.

[rocketmouse at archlinux ~]$ gksudo -u chuser xterm

Doesn't open xterm, no display error or any other output appears.

[rocketmouse at archlinux ~]$ xhost + ; gksudo -u chuser xterm

While running a X session by the user "rocketmouse" this will open xterm
with a prompt for the user "chuser".

Instead of xhost + you're free to use xhost a little bit smarter than I
do.
