QuestionDeveloping open apps Pin

know I'm dumb... really... but what am I missing here - (apart form a screw or two...)

I've never developed an app for a mobile device in my life, but every time I look into it, it seems so incredibly... complicated.

For a native app I suppose I can understand that, but there is much talk now of cross-platform "open" apps built using HTML, CSS and JavaScript as single page applications (SPA's) and then bundled up into some kind of wrapper for the various devices. This should be a simple nut to crack - but even this seems to involve a whole load of sledgehammers...

Suppose I want to build a simple app that asks you to enter your name, click a button, and it will say Hello to you.

I could write this as a simple web-page:
<!DOCTYPE html>
<meta charset="utf-8">
    <title>Hello you</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
<script type="text/ecmascript">
function sayHello(){
    document.getElementById("ur").innerHTML = 'Hello ' + document.getElementById("txt").value;
    document.getElementById("iam").style.display = 'none';
    document.getElementById("youare").style.display = 'inline';
function goBack(){
    document.getElementById("txt").value = '';
    document.getElementById("iam").style.display = 'inline';
    document.getElementById("youare").style.display = 'none';
    <div id="iam">
        <input type="text" id="txt" style="width:200px;" maxlength="25" /> 
        <input type="button" id="btn" value="Say hello" onclick="sayHello()" />
    <div id="youare" style="display:none;">
        <div id="ur"></div>
        <input type="button" id="goback" value="< Back" onclick="goBack()" />
SO... my question then is: what else (avoiding sledgehammers) do I need to do to wrap this up as an open cross-platform app for smartphones? Or am I barking up the wrong tree (in the wrong forest, even)...?
