It is an interesting question.
If you were to have even started this and asked the question by posting an incomplete workbook one step at a time you may have got a more responsive answer and you may have learned something while you did it.

Break your task down into the component parts.

1) Write the blank workbook to match the pdf question.
2) Map the program steps required to perform the tasks.
3) Write each step seperately using the net to ask about each question, learn how to do each step.
4) Apply buttons and code.
5) Debug testing that all works.
6) Write comments into your final code.

Hey presto you would be done and may be able to do it again in future.

Good luck.
