you have to write this code in your java program

Class.forName("sun.jdbc.jdbcodbcDriver");
Connection
con=DriverManager.getConnection("jdbc:odbc:databasename");

Do u mean you want to display some data on a panel/frame designed in Swing?
if yes use JDBC, generate a data-structure, use the data to disply

Let me know if u need help in this

To access database  you will need JDBC, not swings.
