I intend to use OpenCV for a project in which I've already built the server in Go. However, OpenCV doesn't have a Go API, so what's the best solution? Call a c++ program with .exec, use swig, find another library to do computer vision?
Thanks.
Edit: I want to maximize performance, and I'm ok with C++.
SWIG is certainly a viable option.
You can also search for a Go binding to OpenCV. For example: https://github.com/lazywei/go-opencv

Basically is there any way to render a pixel using C/C++ without using any external library. All mingw or gcc headers may be used.
You cannot render images to the screen without external libraries, unless you do hardcore system programming (see for instance this answer fore more information). But you can easily render images that you can save as PNG/JPEG/TIF files, which is what I believe this library is doing.

Just wondering what a good place to start would be? The program I eventually hope to make is a calculator for a windows operating system (School project)
Provided that you have good command of C++, Qt can be a good cross-platform starting point.
Depening on the platform, you may choose to try native OS UI framework; MFC is Microsoft-only and somewhat confusing.
My money is on Qt.

How can I make my own GUI library e.g. SFML?
This question is for the purpose of understanding how GUI libraries work, not to actually make my own library.
I asked what I needed to do so. Can I open my editor and write some C++ code, importing some libraries and that's it. Or it's more complicated?
A library is "just" a bunch of classes and functions, so you write it like a normal program. The only thing that is different is when you compile it: you have to create a static/dynamic library file.

Question is the title.
I'm sorry, I suppose I need to specify.
I'm not sure what commands or what code to use to actually link wget to a gui.
I have two weeks until classes start and I just want to Create something.
Maybe here and here. There are numerous widget toolkits for C++.
Since wget is not a HTTP library, but an application, calling this using system() or similar calls is disrecommended.
I advise you to use a HTTP C/C++ library.
