a quick howto:
1) launch umodwizard & select ut2004, the correct path to your game is needed.
2) create a group (name does not matter) by clicking on "create group", and add some files by clicking on "add files"
3) when you've finished adding your stuff, it should look like in this picture.
4) ini entrys, skip this page by clicking on "next", it's not needed for a mappack anyway.
5) add some requirements, like ut2004 with minimum 3355 as version or jailbreak greater or equal 2004b (hint: 2004b version of jailbreak is number 102, i've just entered 2004b for demonstration purposes)
oops no more picture space left
