check marking and highlighting specific cells

In excel 2003, when I select a cell on any row I would like to automatically
have a check mark placed in the cell on my "J" column of that row. I am
hoping to have all selected cells, including the checked cell, highligted in
yellow and have the data underlined in the cells. But the Check cell need
not be underlined just checked and highlighted in yellow. Ultimately I'd
like to be able to do this with my stylist pen. Is this doable and can you
help me out with doing this? thank you in advance
