I have almost that for sh:
### ~/.profile: sourced by bourne-compatible login shells.
### If ~/.bash_profile exists, this will NOT be read by bash!
### SUS bookmark: http://www.opengroup.org/onlinepubs/009695399/
# [unrelated code elided.]
## The naive "chsh -s /usr/bin/screen" breaks scp (and other things).
## Have sh start screen automatically "when appropriate". That is,
## 1) not in a screen window (STY);
## 2) stdin is a tty;
## 3) screen is installed; and
## 4) terminal is capable of displaying screen.
## Replace "$STY" with "$STY$SSH_CLIENT$SSH_ORIGINAL_COMMAND" to avoid
## nesting screens when sshing (untested).
test -z "$STY" -a -t 0 &&
{ type screen && tput clear && tput cup && ! tput hc && ! tput os
} 2>/dev/null >&2 && # ignore boring, expected error messages
{
## Set the window title to the host name.
## Note that using echo -e \e for ^[ is not portable.
type uname >/dev/null 2>&1 &&
test -n "${HOSTNAME:=`uname -n`}" &&
case "$TERM" in
screen*) printf %bk%s%b%b \\033 "${HOSTNAME%%.*}" \\033 \\0134;;
esac
## If new session, start agents.
screen -ls | grep -i 'No Sockets found' >/dev/null 2>&1 &&
eval "$(twb-agents)"
## Start screen.
exec screen -DRR
}
## If execution reaches this point, screen isn't the login shell. In
## that case, if this is a bash shell, it's a good idea to do the
## bashisms in .bashrc.

I'm not sure if you can do exactly that. I suppose it depends if you're
starting xterm from within the screen session, or from some other X
client. When STY is set you can just do "screen foo" and it'll pop up a
new window running foo inside the screen session. Otherwise you might
be able to do something like "screen -X screen && screen -xRR" to first
start a new window, *then* connect to the session.
