Hi there,

I've been learning C++ for awhile now and is mostly done in Windows OS. ( MinGW, no IDE just using Notepad, PREFER raw stuff... )

From my book and some online sources, most of the functions that I can access is basically just the Hard drive ( read / write file ), RAM ( assigning variables ) and CPU ( doing arithmetics and logic ).
Everything seems FINE at first, but soon I realized something is missing. From my book, every program I wrote always run in the Command Prompt.
But a practical program should have Graphical Interface, control Audio and receive input from Keyboard and Mouse and such.

I learned that in order to have those functions, I need to install extra components ( libraries ) in C++ such as SDL, OpenGL and stuff like that. ( which is not mentioned at all in my book... except and other basic stuff )

So, I would really appreciate someone to explain a bit about these "components".
How and where can you find these thing and what does it actually do to the original C++?

If possible, please provide some guides for me...
I'm trying to create a basic "Tone Generator". A simple program where you can "draw an audio wave form" and the program will "play that wave form from the speaker". It seems easy at first, but couldn't find any libraries that does that...

I don't think SDL (Simple DirectMedia Layer) and OpenGL would necessarily meet the needs of a typical User Interface program, but it would be useful for Audio functions. You would probably want to either install the Windows SDK (I have no idea how well it would work with minGW) or use a UI Toolkit such as GTK or QT.
