How to create a popup when hovering over specific words in UI.text

Hello,

I was wondering if it's possible to create a pop up window that appears when you hover your mouse over specific key words in a UI.text object? I'm dynamically building UI objects for a Google Sheet using G2U and I'm populating a UI Text object with strings of data. In the string I have key words that I would like to be able to hover the mouse over and it would have a popup (like mmo style over icons) that would provide detailed information about the keyword.

Is this possible? If so, could someone provide a very basic example? If this is not possible, any suggestions on alternatives? SolForge is a good example of what I'm trying to accomplish. They have key words and when you click on them they give a detailed description. I'd prefer a mouse hover, but I would settle for a mouse click if needed.

Thank you all for your time and assistance, much appreciated. -Madix
