This isn't Google. Put some effort in asking your question. What exactly are you trying to do? What parts have you go out? What have you found on the web? Why was that not the information you were looking for?

@shaanveer How did the Godot tutorial go?

You've returned to this imgui thing once again, and it's fine to not let something go, but you have to understand that forum correspondence likely won't result in easy code for you to copy and paste over in your project.

You've been shown tutorials out there which you can follow, repeat and tinker with to learn. You'll be able to build that calculator, eventually.

That's great! So with all the Godot tutorials you saw now finished, you're able to position buttons whereever you want, and link their events to your scripts.

They touch on common UI elements here, and a more comprehensive tutorial here.

It's really cool that you took the time to finish them all - now you're able to do so much.

I wrote a very simple calculator for practice using HTML and JavaScript. Run on playground

Source code:

<!DOCTYPE html>

<html>
  <head>
    <title>Very Simple Calculator. JavaScript, ES6</title>
  </head>

  <body>
    <h1>Calculator</h1>

    Enter the first number: <input id="firstNumber" type="text" /><br>
    Enter the second number: <input id="secondNumber" type="text" /><br>
    <button id="btnSum">Sum</button><br>
    Result: <span id="output"></span>

    <script>
      // Get the first number element
      const firstNumberElement = document.getElementById("firstNumber");
      // Get the second number element
      const secondNumberElement = document.getElementById("secondNumber");

      // Calculate the result
      let result = 0;
      const btnSum = document.getElementById("btnSum");
      btnSum.onclick = () => {
        // Get numbers
        let firstNumber = parseFloat(firstNumberElement.value);
        let secondNumber = parseFloat(secondNumberElement.value);
        // Result
        result = firstNumber + secondNumber;
        // Output
        const outputElement = document.getElementById("output");
        outputElement.innerText = result;
      };

    </script>
  </body>
</html>
