do u have any experience as a developer? then go to https://doc.odoo.com/trunk/web/module/

There u will find a simple tutorial to build ur own custom web module.

hope this helps, greetz

requirements:

- postgresql installed and running, other python dependency installed

- do these at odoo root folder

- postgresql username 'openerp' existed and have been granted to create database

- in these commands: Postgresql Database name = odoo_sf_db, modules directory = sf_modules, module name = sf_module, model name (will be a table name in Postgresql database) = sf_model, controller name ( it is the code to process some web requests) = sf_model_controller

createdb -U openerp -W odoo_sf_db

./openerp-server scaffold --init sf_module --dest sf_modules --model sf_model --controller sf_model_controller

cd sf_modules/sf_module/data
vi sf_module_demo.xml

then change the line:
<record id="sf_module.sf_model_demo" model="sf_model">

to
<record id="sf_module.sf_model_demo" model="sf_module.sf_model">

cd ../..

./openerp-server --addons-path=addons,sf_modules -i sf_module -d odoo_sf_db -r openerp -w admin1234

after some minutes, open your browser to:

http://localhost:8069

to see your new 'web page'

and
http://localhost:8069/sf_module/sf_model_controller

to see your new 'web page' with the result from your model controller.
