Excel 2010 :: Code For Inserting And Removing Dates

I need a code that when i place a date in a cell D10 (Example:25-January-2013) it will then add 40 days of dates daily to AP10.In D9 can it also add the weeknumber (every 7 days the weeknumber increases by 1) corresponding to the day date in D10 (iso).Can this be attached to a button.Enter the date in D10 then press the button and the dates auto insert across the sheet daily to AP10.

Can the button say ADD DATE or REMOVE DATES.First date in D10.When the button says REMOVE dates all dates deleted when button pressed and cell D10 then says "add date here".If no date is placed in D10 and ADD DATE button is pressed a warning messagebox appears and says NEED TO ADD DATE .Will not work until date entered.When date entered in D10 "Add Date Here" disappears until REMOVE Date button is selected and again "Add Date Here" is displayed....not sure if this is possible but would be good if achieved.
