title: Are there any basic immediate mode gui tutorials?
body: <p>I am trying to find any basic tutorial which could show me how could I do immediate mode gui. I know it is a really hard thing to make own gui. I have already tried to make retained gui (it ends up being very basic). I have been looking for any im gui tutorials for a long time, but could not find one. I've tried to read ImGui lib, but some things are hard to understand. </p>
  
  <p>Do you have any vidoes, books, ...?</p>
  
  <p>Could you give me some advices how could I make that type of gui.</p>
  
  <p>I do not want to use external libs. I want to learn something.</p>
