How connect GSM (cellular-phone) to microcontroler, reading

[Michel]

Well I think I'll start with PIC as my first microcontrol project,
although PICAXE seems to be a nice think to! Though I have an other
question/problem:

I like to build a doorphone/door-code-lock through a GSM-phone, so
Can I hook up a GSM (cellphone) and be able to autoanswer and read in
the phone-dial-tones for remote controle? And can I call out using the
hooked-on cellphone to let me communicate with the person on my door?
Maybe with my old Nokia 6110 or Motorola Startac?

Thanks for already reading this!

PS: It seems I could not react through Google to my other post-replies
on:
"Is there a all-future build in microprocessor for a beginner?"
and "I'm looking for (cheap) easy programable little
pcb-microprocessor"
I get "Unable to retrieve message
a9ee3bbf.0412191300.7a2a9760@posting.google.com" !!!???
Any idea what I do wrong?

Thanks for the answers on that!
