Add Column & sheet with Button

Hello,
Can someone point me in the right direction?

Im looking to have a button that will do a few things.
-insert a new column (with the same formula as adjacent ones)
-fill in the value of cell on row 5 with the initials in cell "C20"

-create a new sheet (COPY OF EXISTING USER SHEET or a blank template from user sheet)
-rename the sheet with the initials in cell "C20"
-copy value of C21 into new sheet cell B1

- clear contents of MASTER cell C20 and C21


is all that even possible?
TIA.
