Flash card system -- 2

Flash card system, as seen on: [login to view URL] Basic back end control panel to add / edit sets of flash cards Flash Cards to be stored in MySQL database I also want to be able to tag 'words', in my site pages, (using a DBQuery) to call the database for the definition, then display it in a pop up. ie. Flash Card Title is: Thermal Definition: Generating or caused by heat In passage of text in my site, I highlight the word 'Thermal', when clicked a pop up shows the definition stored in the database.
