Using Webform Hooks to submit and display custom module forms?
Webform has nothing to do with your form if you created it in a module.Your form is a form not a webform type node.
Form API! reference is what you need and to install Devel module

Then 

dpm($form)


inside your form builder function to check which function is your #submit which is your #validate and add[] your own if you like

form values are stored in $form_state array
dpm($form_state) it also in your submit function and do whatever you want with these submitted values.

Store them in drupal database using variable_set() , mail them using drupal_mail() etc.
