At phpwizard.net you can get phpMyadmin which is a PHP frontend for a MySQL DB, you don't really need to know SQL to use it, there are limited frontend applications already programmed. However it does help.
If you're having trouble learning SQL you could use Microsoft Access. You could design a query using its query wizards and whatnot and them you can change your view to SQL View and see the sql source of the query. I know you asked for MySQL but you should know that SQL is more or less the same across platforms and applications, there are a few minor differences but for basic applications you should easily be able to apply SQL from Access to MySQL.
