This question is too general. The only correct answer would be writing a sample site for you, which is beyond the format of Quick Questions & Answer. Keep searching and trying, there are not top secrets in this kind of development. Google for some other solution.
Better yet, try to create a simple prototype not using the whole code somebody created, but just using the ideas you learn from it. Make is as simple as possible at first. If it does not work for you, ask more specific questions here related to your code — we would gladly help you.

Answering a follow-up question:
For a pretty good and simple ADO.NET introduction, see, for example this CodeProject article:
