Help for beginner 3d modelers

No,there is no standalone programs but there are several md3 export scripts for blender.You can also export your model to .3ds or .obj,then open it up in milkshape,create quake config file and export your model(it must have the same name as the config file) to the same directory your config file is located.
The only problem is that this way of exporting 3d models eat your animations that you made in blender.Im sure you can find another export scripts and plugins in google and youtube too!
