title: Displaying an overlay above another program
body: <p>I have a program to display some additional information in a third party application.  Originally, the third party application had a simple API that allowed me to create text objects; but it's since been removed in a version update.  Using the legacy version is not an option.</p>
  
  <p>Is there an easy way to do this?  I basically just want a few lines of easily updatable text that are positioned relative to the host window, have a transparent background, minimize with the host window, and do not interfere with the host window's processing of keystrokes or mouse.</p>
  
  <p>Apologies if this isn't the appropriate place to ask this question, I did search the site but I couldn't find anything that seemed to fit my needs.</p>
