Answer 1

I have only found that you have to use "StringVar()'s" in order to update the labels.

This is not a true statement. You can update the attributes of any widget with the config / configure method. Starting with your first example, it would look like this:

myLabel = Label(root, text='myText')
myLabel.pack()
myLabel.configure(text='new text')

And, in your final example:

table.getRow[0][0].configure(text='new text') 

As for the bonus question, yes, it's possible.You can bind any code you want to a label just as you can any other widget, and in addition to bindings on keys and mouse buttons, you can bind on gaining and losing focus.
