Create a NSIS installer for my software

I need an installer for a little software I made. I suggest to use NSIS to create the script because I need to be able to edit the script for later updates of my soft. Installer pages: 1) language choice 2) license acceptation 3) ask for express intallation or custom 4) if express: display what will be installed if custom: display what can be installed with check box 5) ask for program files path 6) ask if want a desktop icon and quicklaunch icon 7) instalation and if an option is checked in custom install (or express install choosen) run a file(exe)
