Java PostgreSQL

I want you to help me to build a simple program with Java (IntelliJ IDEA) and PostgreSQL.

The idea here is not to build a complete program, rather help me start to save time in the start up and help me alter and build on it.

2- Drawing:
Reads coordinate of simple geometric object from a table
Draws object on canvas in TWO(2) ways:
