interactive telnet/netcat script help

I am wondering if it is possible to write an interactive script to run telnet or nc. I want to write a graphical front end with menus (default selections and such) for point and click... a telnet server is on the other end.

The issue I have is that the connection can't be broken once started. I can't have a program flow like this:

Code:

first:
 (item 1 selected)
   telnet << item1script
   (connection broken)
then:
 (item 3 selected)
   telnet << item3script
   (connection broken)

The script has to flow like this:

Code:

start_telnet
 (item 1 selected)
   send_command_1
   receive_data
   display_data
 (item 4 selected)
   send_command_4
   receive_data
   display_data
 (item 1 selected)
   send_command_1
   receive_data
   display_data
 (quit selected)
   connection_broken_and_quit

Is this at all possible? Maybe someone already has this capability written? I have been on google for hours... Any help would be appreciated, thanks in advance.

BTW: the interaction has to be dynamic, as the next choice is determined by the return data. I am using this to control the target host in an unusual way, and the menued script allows for far less typing on my part - also, it will allow others to have the same setup without difficulty.
