I need a simple matlab program

Problem: Design a GUI-based tool that can aid an engineer in performing important engineering tasks. The tool can perform the following tasks: I. Perform Arithmetic. 2. Perform Conversions 3. Plot Functions. 4. Symbolic Math Details: Once the tool is run it should display a dialogue box that shows four options corresponding to the four tasks the tool can perform. The user is allowed to choose one task at a time. The four tasks are described below Task 1: Arithmetic Once this option is selected, a calculator is shown with numbers from 0 to 9 and with buttons to perform the simple arithmetic operations, namely, addition, subtraction, multiplication, and division. Assume that the calculator adds integer numbers only (that is, numbers with fractions are not supported by the tool). The calculator should also have a button that allows the user to go back to the original GUI. Task 2: Conversions Once this option is selected, a dialogue box appears to ask the user about the type of conversion he/she desires. Four conversions are supported, namely, converting temperature from Celsius to Fahrenheit, converting angles from degrees to radians, converting lengths from meters to feet, and converting mass from kilogram (kgs) to pound (lbs). Once the type of conversion is selected, the user is asked to enter the value to be converted. GUI where conversions are handled, there should be a button allow the user to go back to the original GUI. Task 3: Plot Functions Once this option is selected, a dialogue box appears to ask the user whether he/she would like a 2D plot or a D plot. After that, the user is sked to enter the function he/she desires to plot and the ranges of the axes. The tool
