Is there a way to present the GNU Screen session name and window title in the prompt of the shell (let us say, the Bash prompt defined by PS1)?

Screen supplies some environment variables (from screen(1) manpage):

STY              Alternate socket name.
WINDOW           Window number of a window (at creation time).

The "at creation time" means that if you renumber a window (using screen's number command), the shell will not be told about the change and $WINDOW will still be the same as the first window number.

You could use something like:

PS1='\u@\h(${STY}:${WINDOW}):\w$ '

Perfect! This is what I was looking for. BTW, there is a way to get the window title, instead of the window number? –  brandizzi Sep 19 '11 at 1:13
Not that I know of, there is no api for screen, and when you issue commands there is no output - it goes to the current window in the screen. For example screen -xr 2466 -X windows. –  Arcege Sep 19 '11 at 1:26
