embed postgres

Hi, I am looking to embed postgres into an application on windows. I am fine 
with it being a separate service. Here is what I am looking to do. Any help 
would be greatly appreciated.

1) Install postgres silently. Libs (dll) and data files.  a) What are the minimum files dll.  b) What .conf should I
editto state where the postgres home is located?
 
2) Start postgres when the app starts.
3) Stop postgres when the app stops.
4) Minimize the amount of postgres processes.
