Get list of node dependencies
Drupal does not know "dependencies" on it's own, so I assume it's something provided by the module you named. Yes, it is possible. After all that module is doing exactly this. Just read it's code and see, PHP is an interpreted language after all. It seems there is no module with that exact name on Drupal.org, so I can't provide more detailed instruction now. To find it yourself, you need:


Find implementation of hook_menu() in this module
Locate entry for GUI page that shows what you want
Find implementation of a function that obtains data for that GUI page
