(Sorry, I overread the preexec part.)
So your problem is not to set a title in xterm.
Your problem is that PROMPT_COMMAND is applied _after_ the execution of the
command.

Do you want something like this?

.inputrc:
        "\C-m": "\C-apreexec \n" accept-line

I do not know a better way to do this in bash, Sorry.
