I have the library called Serial.dll that containts the file Serial.def that looks like this:
EXPORTS
ValidateSerial
GenerateSerial
I want to import the function GenerateSerial in my C++ Win32 application. I searched on the internet topics about using DLLs but I can't get the idea... Can anybody help me?
The info you provided only tells two funciton names. You can obtain their address doing LoadLibrary and GetProcAddress. But to make any use of them you need to know the proper signature, and the rules for the arguments and return values.
Without documentation (or a .h file) you can't go very far.

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

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.

I would like to know if I can run a DLL function from a exe?
(C++ if it's important)
And If I can can I do it with parameters?
This isn't really code but the concept is the same
Run Calculator(time,0,int,max)
I would like to run something like that, using parameters to open up the dll in a certain way. Is it even possible?
Bonus Point for anyone who can give me an example in code :)
You can have just about any function you like in a DLL, and call it, just as you would call any library function. And have as many parameters as you like.
