Not sure I entirely grasp what you are trying to explain, but creating custom forms is quite simple. This is from another post I wrote some time ago:
To modify the forms you can either provision the list using custom list forms or use SPD to create a new display form. Open the editform.aspx or newform.aspx of the list in SPD. Select the entire form and delete it, or you can just select 'default to master content' from the smart tag to remove everything. If using the latter approach, select Custom content from the PlaceHolderMain smart tag and place your cursor where you want to custom form to be placed. Then, go to Insert->SharePoint Controls->Custom ListForm. Select the appropriate options in the dialog and you should now have full access to customize your form, including replacing any editable fields (SharePoint:FormField [...] ControlMode="New") with displaying fields (ControlMode="Display").
If you are trying to have multiple forms in a single page you should be able to accomplish this as well, but you may need some more fiddling.
