this GUI as simple as it is explains some basic but important graphical database interfacing; "Add", "Edit","Delete","Search" and few others along with a data grid view. in order to work create an sqlite3 database as follows:
data table : Phone, column 1 : ID, column 2 : name, column 3 : surname, column 4 : telephone.
save the sqlite3 file as file.db in a folder called Data and place it in the same directory as your python script.
if you want to create the sqlite3 database graphically use my previous post : http://code.activestate.com/recipes/578665-a-wxpython-gui-to-create-sqlite3-databases/
Also there is more: I did not use auto-number for 'id' because I also wanted to include in the code a renumbering script.
I am pleased to receive all the suggestions and improvements on this site or to my e-mail directly if this is convenient to you.
note: if you don't like the database table name, and columns name create your own but make sure to change them in the code as well! in the end life is great! remember that!

How to insert more than one button or label on a single cell of table(grid)
I guess what you want to do is editing and deleting a row in the grid by clicking on a button that is in a cell of this same row.
Use grid events wx.grid.EVT_GRID_CELL_LEFT_CLICK() And associate this event to what you want to do. Or you should add buttons next to the rows of the grid and not inside of it. It means on each row addition create a button next to it. Other than that I really don't have any idea of how it might be done simply without rendering cells and complicating life more than it is already :). Check this
