The closest to "bringing up an Emacs window" is to invoke the program
"emacsclient" (with one or more filenames as arguments).  emacsclient
sends an IPC message to your Emacs (which must have previously run the
command 'server-start').  Emacs receives the message, and brings up a
window.  When you type C-x # at the window, Emacs sends an "I'm done"
message to emacsclient.

If you want to communicate text with the Emacs, you have to put it in
files (unless you want to hack the client/server code), but that is
not unreasonable.

As far as I know, there is no way to use emacsclient to force the
buffer into a particular mode directly, but (since the server code
uses find-file) you can use the extension to force the buffer into a
mode (see var. auto-mode-alist), or use local variable settings in the
text file.

Perhaps emacsclient should be modified to support some of the Emacs
startup options (+linenumber, -f function, etc.).
