Of course it is possible. A launcher in the Unity sidebar on the left is just an easy-to-use shortcut for launching your application.

You can do this, once you've found which is the correct command so as to execute your program. After you are sure about this, according to this you could create your own desktop file. Just edit the Exec (command to execute), Icon (icon to display), Comment, Name (name that will be displayed) etc fields from this example file:
and save it as anything.desktop Then, move your desktop file to ~/.local/share/applications and search it through the Unity Dash, according to the name you've given to it inside the 'Name' field. Launch the application and lock it to the launcher.
