Does go-gtp allow to create the GTP headers? about go-gtp HOT 2 CLOSED

You can create the packet with message.NewTPDU and marshal it into a binary with Marshal(). Then you can write it to UDP conn.

import "github.com/wmnsk/go-gtp/gtpv1/message"

msg := message.NewTPDU(teid, payload)

b, err := msg.Marshal()
if err := nil {
    // ...
}

if _, err := conn.WriteTo(b, raddr); err := nil {
    // ...
}

If you need to set values to more fields in GTPv1 header(other than TEID), create the message from Header struct by yourself instead.

msg := &message.Header{
   // ...
}

Hope this helps.
