how to run a module?

I have made a module, named module1 whose function is to make table1 on which a query1 will be built.
1- What code shall I write in a bottom to run module?
2- Can I make the whole process by one bottom? I mean can I get the final query by just one click, or do I have to run the module to first have the table in hand and then run the query over the table?
Thank you
