Making a torrent file is one of the easiest things to do. For that you need these things, uTorrent, the file which you want to share and a tracker. I will be using demonoid tracker for this torrent and Flock Browser setup just to show you how to make torrent file in uTorrent. You can use any tracker you want like thepiratebay or any other.

First of all, open uTorrent. Go to File > Create New Torrent

After you click Create New Torrent, a new dialog box will appear. Click add Directory and give the path of the folder you want to have in the torrent. In my case i used the flock browser. Also give the tracker URL which you can find on tracker site where you upload your torrent and also check Start Seeding.

Then click Create and Save as and chose the location where you want to save you torrent file. Once you save the file it will bring you back to the Create New Torrent dialog box where you can enter any comments you want to add. Click create and save as again and you are done. Now Just add the torrent in uTorrent and Right Click on the torrent you just added. Now click Force Start and it will start seeding the torrent so others can download it.
