title: PySimpleGui - Get Button Text
body: <p>I'm developing an app using PySimpleGui that will assign button text from a list. The text on the button(s) will change by users as they search. I want to be able to read, print and assign the button text when the button is pushed. How do I do that? Here's the code. I've tried several things to no avail. Two print statements at the end of the code are remnants.</p>
  <pre><code>import PySimpleGUI as sg
  
  selection_button_text_data = ['Like a Rolling Stone','Bob Dylan','The Sound of Silence','Simon &amp; Garfunkel','Respect','Aretha Franklin','A Day In The Life','The Beatles']
  
  layout =[
      [
          [sg.Button(selection_button_text_data[0])],
          [sg.Button(selection_button_text_data[1])],
          [sg.Button(selection_button_text_data[2])],
          [sg.Button(selection_button_text_data[3])]
      ]
          ]
  window = sg.Window('Window Title', layout)
  event, values = window.read()
  window.close()
  print(values)
  print(sg.Button.GetText())
  </code></pre>
