Here’s a really quick way to add a button into an existing page and then have the button call a function that is within greasemonkey script.

 
window.addEventListener("load", function(e) {
  addButton();
}, false);
 
function addButton(){
 var buttonElems = document.getElementsByTagName('buttonElementName');
 buttonElems[0].innerHTML = buttonElems[0].innerHTML + ''
addButtonListener();
}
 
function addButtonListener(){
  var button = document.getElementById("greasemonkeyButton");
  button.addEventListener('click',doMonkey,true);
}
 
function doMonkey(){
	//do something
}
