Inputing data to a relational database

I am a nebie to Mysql/php and am currently working on an urgent project, a on-line catalogue. I have been using phpmyadmin, to create the tables in MySQL. However I now want to add data into the tables. I am reluctant to program a php page to do this, as I do not (yet) have sufficient php knowledge. As far as I can see phpMyadmin doesn't do all I need it to, which is:- The tables reference each other, for example The categories are stored in a categories table The products table includes a field category to ensure referential integrity, when adding a product to the products table, I want to have a combo box that will let me select one of the categories from the categories table. Is there anything like phpmyadmin that will let me do this without me having to write code. Any advice much appreciated Nathan Roberts
