The default prompt has escape sequences that change the window title, so
that it contains the current working directory.  So unless you change
PS1, no matter what you do to set the title it will be overwritten on
the next prompt.

You can do this with a simple shell function.  For example, with the
following in your ~/.bashrc:

settitle()
{
  local t=$1
  if [ "x$t" == "x" ]; then t='\w'; fi
  PS1=$(perl -e '$_ = $ENV{PS1}; s,(\\e]0;).*(\\a),$1$ARGV[0]$2,i;
                 print' "$t")
}

... then you can just

settitle foo

or if it contains spaces:

settitle "foo bar"

or even including prompt escape sequences like:

settitle "dir: \w tty: \l foo bar"

or just "settitle" to get the default of \w.
