Where to start for macking an application

[imangh]

Hello
I am a new bit in Linux programming.
A new Project I want to start is a recording system for a device in a factory, I must read some information from Serial input and Save them and show a graphical diagram.
The bootup time is very important because each second before system be ready, program will miss some useful
information.
I need tcp/ip and sockets also Graphc mode, I want to know is there any way to use Graphic mode in text mode of linux (like graphic initialization in
DOS).
Anyway, would you please let me know where I must start(programming language, libraries, ...).
I have some experience with VC++,C# and good skill with PHP.

you can use gtk-c
or python
for graphical interface.
