Browse and edit form for simple MySQL table(repost)

I have a simple table. I need a browse and edit form for that table. Only? 2 fields of that table will be shown in the browse list and only these? 2 field will be edited in the edit form. In the editform the following? validations? must be applied: 1. All? 2 fields must be filled, thay may not be empty. 2. The first field must be unique. If a user tries to Add or Modify a record and there is already a record in the database with the same first field value, an error must be issued. It must be possible to add/modify/delete a record.
