You don't need a project file to compile a hello world program. Since 
you have Gnat you should put that in a file named "hello.adb" and then 
run "gnatmake hello.adb". This should produce an executable file named 
"hello.exe".

I think you should let the Gnat project files wait a bit. Right now you 
can think of them as something GPS uses to store the settings you make. 
Later, when you're more familiar with Ada, you can start learning what 
Gnat project files are useful for.
