The standard modeling program that almost all modders use for Unreal Tournament games is the Maya PLE. Alias offers a "Personal Learning Edition" of Maya that you can download for free. The only limitations there are is that if you render a scene, there will be a watermark on it., but there will not be one on your models, only if you render. There is an exclusive plug-in designed specifically for the PLE, so you can export any content from Maya PLE, directly to UnrealEd, player models, weapon models, static meshes, anything.
Here are some sites to get you started.
