title: What R package or code can be used to build custom-made GUIs?
body: <p>I am looking to create GUI that takes in a few inputs from the user (for example gender, age, and race as clickable categories), then assigns a user ID to each input (which would be displayed as the output in the GUI).  Under the hood would be a dataset that the GUI is creating with this user input (In this example, it would be 4 variables: user ID, gender, age, and race).  </p>
  
  <p>Has anyone created a GUI like this before?  Any R package or code recommendations?</p>
  
  <p>Thanks!</p>
