• D-Recruitment Center is in the business of matching computer systems analysts and programmers with employers needing temporary help. They pay a flat rate of GHC 150.00 per hour to their contract analysts and programmers. Contractors are paid on a weekly basis or at the completion of a project, whichever comes first. Each contractor logs his or her own hours. They have asked you to develop a Windows application to be used by the contractors to determine how much money they will take home for a given period of time. D-Recruitment Center is required by law to deduct Social Security taxes (SSNIT) and withhold income taxes from each check. The amount of SSNIT deductions is calculated at 7.85% of the gross pay. The amount of withholding is based on the number of dependent allowances. The following formula is used: Withholding Tax = (grossPay - (gross pay * 5.75% * number of dependents)) * 25%. They also charge a membership fee to each contractor of 13% of their gross pay. Design a GUI that will accept as input the contractor’s name, the number of dependents, and the number of hours worked. Display the gross pay, SSNIT deductions, Membership fee Deduction, Withholding Tax, and NET pay.
