Is there an example of simple non-interactive iapp that configures a profile, monitor, node, pool, and virtual?

This should work for you:

    sys application template /Common/f5.hardcoded {
    actions {
        definition {
            html-help {
            }
            implementation {

proc tmsh_create { args } {
    set args [join $args]
    puts "tmsh create $args"
    tmsh::create $args
    return [lindex $args [lsearch -glob $args "*_*"]]
}

tmsh_create ltm virtual ${tmsh::app_name}_vip \
    destination 10.10.10.1:80 \
    pool [tmsh_create ltm pool ${tmsh::app_name}_pool \
    members replace-all-with \{ \
        10.1.1.1:80 \
        10.1.1.2:80 \
        10.1.1.3:80 \
    \} \
    load-balancing-mode least-connections-member \
    monitor  [tmsh_create \
         ltm monitor http ${tmsh::app_name}_http]] \
    persist  replace-all-with \{[tmsh_create \
         ltm persistence source-addr ${tmsh::app_name}_source_ip]\} \
    profiles replace-all-with \{[tmsh_create \
         ltm profile http ${tmsh::app_name}_http]\} \
    ip-protocol tcp \
    snat automap
            }
            macro {
            }
            presentation {
section intro {
    message hello
}
text {
    intro "Hard-Coded Implementation"
    intro.hello " " "Just click Finished."
}
            }
            role-acl none
            run-as none
        }
    }
}
