Change default "create ticket" layout

Hello,
Is it possible to change the default “create ticket” layout (removing some fields like CC, subject and the “Describe the issue below:” fields) and only use custom fields ?
If so, how can I do it ?
Thanks, Philippe.

You have the source to RT and can customize it as needed, although if
you’re going to make such drastic changes, you may wish to simply
write an external form that communicates with RT.
