[drupal form]

i am trying to write a form in drupal, here is my plan. I have a database of players name and number, I would like to write a form that allows user to change players number, my question is how would i create a form that display values from the database? The initial form would be players name (title) on left side (name are taken from database) and players number (textfield) on right side with default value from database.

I guess my question is how do you display dynamic values in drupal form, instead of hard codeing?
