Creating Application

I need someone who can create a light stand-alone application that can do the following: 1) Converts spaces to dashes 2) Deletes all comma and dollar signs 3) Converts all remaining special characters stated above as dashes 4) Output will be lower case. Other features of the application are: 1) Maximum input characters may be set 2) Copy button so I can just press it to copy what's inside the output field. I attached a sample.
