It is certainly possible to do something like what you want, but the
details depend very much on the system you're running the java
application on, and such things as what window manager you're using.

Under Unix, java applications are often started up from small
shell-script wrappers, which do such things as setup the class path
and then invoke java on the applications' entry point class.  Look at
/usr/local/bin/ant (from the devel/apache-ant port) as an example.
Exactly how an icon might be assigned to that script is OS and window
manager dependent.

Alternatively, look into Java WebStart --
http://java.sun.com/products/javawebstart/ -- which lets you install
Java appications by clicking on a link on a web page.  JavaWS lets you
associate whatever image you want with the application through an XML
configuration file.  It's standard with any J2EE JDK or JRE.

For the connectivity to the SQL database, look at JDBC (Java DataBase
Connector) This is a standard database-independent connector
architecture and API (http://java.sun.com/docs/books/jdbc/) You need
to add an appropriate driver module to let it communicate with the
particular variety of database you're using.  eg. see the
databases/mysql-connector-java port
(http://www.mysql.com/products/connector-j/index.html).
