how to align the label and entry text box in my tk GUI

[fsmendoza]

Dear Perlmonk experts,

I'm designing my simple GUI and i could not find a way to get rid of the spaces between the label and entry box in my output GUI and align them. Please advice on what will be the best way to do this.

Thank you.

+es before you use them
use warnings;                # module to show where is the error 
use Tk;                        # module for the Windows GUI
