really easy, open winzip and tell it to create new archive

it will ask you to name it, this will be the name of the zip file (but its easy to just right click it and rename it anytime you want)

it will ask you where you want to put this file, as default it puts it in your my documents folder so i let it do that

the next window asks if you want to zip a file or a folder, whatever you pick you wont see the other type when you select the location so it may look funny but nothings missing its only showing you the types you selected.

if its a mod your zipping select folders and then highlight the main mod folder then click ok, thats it in 2 seconds your mods zipped, open my documents and there it is. untill you do it a few times unzip it to see it was done right (maybe you forgot to include the read me or whatever). when i first did it i mixed up the name to call the file with the name of the file to zip and had to edit the name lol.
