Hi, I am new to ruby
This is my first my application using ruby on rails. Can anyone please let me know if I can develop an application to conduct an online test and select candidates, using ruby on rails? The app consists of two users: 
i) Administrator (configures the test,whenever required) and 
ii)Candidates (who appear for the test)
Operating system: Windows XP
Also please suggest me one good IDE for ruby on rails (free of cost).

Thanks in advance
