I am creating an unordered list from an array. However I would like the list items to be buttons who's text are from the array? How would I accomplish this?

If you were looking for plain JavaScript then this would work

<body>
    <div id="output"></div>
    <script>
        var theList = ['Update', 'Cancel', 'Delete'];
        var output = document.getElementById('output');
        var getButtonList = function(items){
            var html = '<ul>';
            for(var item in items){
                html += '<li><button>' + items[item] + '</button></li>';
            }
            html += '</ul>';
            return html;
        };
        output.innerHTML = getButtonList( theList );
    </script>  
</body>

That's going to output this:

<div id="output">
    <ul>
        <li><button>Update</button></li>
        <li><button>Cancel</button></li>
        <li><button>Delete</button></li>
    </ul>
</div>

To get a solid solution for your specific problem, you'll probably need to supply your code or some more information about your goal.

Here is a quick and dirty solution to my understanding of your problem, using JQuery.

// Things I am assuming:
// - You have an unordered list on your html page with the id "buttonList".
// - You have an array of strings (myArray below).

// Example Array
var myArray = ["Alpha", "Bravo", "Charlie", "Delta", "Echo", "Foxtrot"];

// Cycle over the array.
for (var i = 0; i < myArray.length; i++) {
  // Create a list item.
  var $exampleItem = $("<li></li>");
  // Create a button.
  var $exampleButton = $("<button></button>");

  // Set the button's text to be the current array item.
  $exampleButton.text(myArray[i]);

  // Append the button to the list item.
  var $newButton = $exampleItem.append($exampleButton);

  // Append this to the unordered list.
  $("#buttonList").append($newButton);
}

// There is probably a better way to do this, but this should work.
