I have downloaded the package 'Kivy-1.9.0-py3.4-win32-x64' from their website. I extracted it and gives me a folder with gstreamer, kivy34, MinGW, etc. As I have searched to some tutorials I clicked the kivy-3.4.bat file to set the paths. Now I'm lost, what to do next? 
I wanted to do Kivy applications through Python IDLE. Help!
Make sure you have PIP installed (it gives the option to install when you download python). Then, open a command shell (CMD on Windows; enter the search bar and type in 'cmd') and type pip install kivy.
Some would recommend setting up a virtualenv and stuff but as a quick answer this should work.
