simple kernel/OS

this may seem too big to start but im trying to start a simple OS starting with a simple prompt written in C or CPP

what im asking for is any articles related o anywhere i can read i tried lots of google searches

i know i need to make a

1. bootloader in ASM

2.kernel

3. GUI (not needed)

i havent done alot of C basically C++ but i was wondering if you could help my thoughts begin to materialise

i started with a C++ terminal type thing but its really basic and crashd often i dont think this is the prper way to do it

#include <iostream>
#include <string>
using namespace std;

int main ()
{

begin:
  string cmnd;
  cout << "\nsimple_shell$ ";
  getline (cin, cmnd);

if (cmnd == "login"){
cout<<"starting GUI interface";
}
if (cmnd == ""){
cout<<"command not found";
	goto begin;
  }

else 
{
cout<<"command not found";
goto begin;
}

return 0;
}

but please any resources you can point me to will help me alot
