no, seriously, it can take a while. but it really depends on what you say is serious.
You could make it really complicated with threading, networking, advanced data structures, graphics, shared libraries, STL, etc, or you could make a useful console program. but each additional facet of programming besides (well, including) standard C++ takes a while to learn to use effectively, but they all build upon C++, so you should have a solid understanding of the core language first. Each of these things can take months, or even years, to learn how to do well.
