MySQL AB does provide a couple different GUI applications that I use frequently (they might be a little bit more fully featured than what you need but I thought they were worth mentioning). The first option listed below is no longer actively developed as they are transitioning to the second option listed (which is currently in beta):

MySQL Control Center
MySQL Control Center (or MySQLCC) is a GUI client that works alongside the MySQL database server. Built using Trolltech's Qt application toolkit, MySQLCC makes it easy to create databases and tables, write and execute SQL queries (in a syntax-highlighting editor), examine the contents of your tables directly, and back up or fine-tune your server setup. It supports both local and remote servers, and all table types.
MySQL Query Browser
The MySQL Query Browser is a graphical tool provided by MySQL AB for creating, executing, and optimizing queries in a graphical environment. Where the MySQL Administrator is designed to administer a MySQL server, the MySQL Query Browser is designed to help you query and analyze data stored within your MySQL database. While all queries executed in the MySQL Query Browser could also be performed in the mysql command-line utility, the MySQL Query Browser allows for the querying and editing of data in a more intuitive, graphical manner.
