are you referring to the lib's this unknown program is using ?
or is this unknown program calling other programs ?

If you want to see the progress of process, you should have source code of the software.

Is your software a GUI application or does it run on terminal?

It is not like softwares are always java based GUI or run on terminal.
A fully developed web application can be treated as software. When you open the web page or click on the button, a number of scripts can be run according to your instruction. You can see those using "Inspect Element" feature.
It shows you what is exactly happening when you click on the button or select a drop down value or run a AJAX or Jquery function.

Same you can get this using debugger for your program. it shows you line by line process of your software.
