what is your best recommendation ? i read some articles . it has mentioned that WordPress can install with WAMP WebServer Application. is it recommending ?

Further I’ve plan to Configure one server for few WebSites developing by outside party. because i want to give separate access for developers. can i do it ? how can i do it ?
