Custom hud and derma panel that can spawn ammo?

I need to get a custom hud and a derma pannel that can give me ammo. Like a custom spawn menu for my gamemode. Also where do i put the things for my gamemode?

Here ya go friend! I cant help with the Derma because it is too much of a pain in the ass for me.
But read that link I pasted and you should be able to learn everything there is to know about Gamemodes

Well what about hud?

Two options here for HUD: draw or surface.
