Anything that can be done in OOP can be done without it. But OOP makes many things easier. But OOP only really becomes useful in bigger programs. If your biggest program is less than 100 lines of code then you probably haven't hit the kinds of problems that OOP solves. Between 100 and 1000 lines you increasingly hit problems of complexity, name collisions ( two things with the same name), and writing nearly identical code lots of times. By the time you get over 1000 lines all of those problems are compounded by the fact that you can't actually keep all the details in your head anymore! Objects help bring some sanity to the procedings. Finally, once you get your head around the concept of objects being like little independant programms communicating via messages then they start to fit certain types of problem very well. THe classic case is the GUI with each window, doalog box, button, menu etc being independant objects, but with a lot of common functions and a lot of inter-communication. When you coule that to the event-driven style of most GUI toolkits then events translate easily into inter-object messages and OOP becomes a very natural way to program GUIs.
