How to run gdbserver and gdb in two different windows?

Hello.
How do I write a script for screen that will do the following:

1. create two screen windows (ctrl-c).
2. execute the following command in the first screeen session:
    gdbserver port:1234 editor text-input-for-editor
3. execute the second command in the second screen session:
    gdn editor

Can someone please give me an example?

Thanks in advance for your kind help.
