2 things are possible:

a) Edit ~/.bashrc with an editor of choice and add an alias line.
alias foo='xterm -e top'
This as an example. You will have to source the changed .bashrc file by
running
. ~/.bashrc     or      source ~/.bashrc
If you then enter "foo" (without quotes) either in the console, xterm or
the starter box queried with Alt+F2, an xterm will open with top running
in it.

b) You may create a shell script instead. First create a bin directory
in your user home running "mkdir ~/bin". Use then an editor of choice
and create a file inside new directory bin in your home directory called
i.e. "dosinbox" with following 2 lines content:
#!/bin/bash
/path/to/dosemu further parameters
Use the proper path to dosemu (though it might not be necessary) and the
correct parameters you like to use with dosemu and your program. Once
saved the file make it executable with "chmod 750 ~/bin/dosinbox". If
you then call "dosinbox" either on console or by creating a starter
(Gnome desktop right mouse button click) the commend will be executed.
