Develop an application that counts the number of words, number of characters with spaces and without spaced. The program should display the text file statistics as follows:

File Name: sample.txt
Number of Words: 124
Number of characters without spaces: 1045
Number of characters with spaces: 1200

The application shall be a counsel compatible application-(needs a GUI)
here's what I have so far...
i'm missing both character counters and am not sure how to get files in my gui
