Code required for Event Program

If I have two buttons event maker and event viewer. Whenever I click event maker it takes me to an appscreen and shows me a button if I click that button a new textbox will appear before me in which I can write all my important things like my friend's birthdays etc. And then when I click on the event viewer button it takes me to a new appscreen where I can only view my important notes which I have edited in the event maker Please help as soon as possible. God may bless all
Hoping for the best
Yours faithfully

I suggest you go to the Gallery and search for "Notes" apps for examples

Thanks for suggesting machine
