You can use execution parameters and something such as Visual Basic or C.

SAMP.exe is basically like a website. It has certain "pages", otherwise known as execution parameters. As far as I know there are only 2 parameters(whereas the latter is optional).

Parameters:
Server IP
Port
Example with both parameters:

Code:

samp.exe 127.0.0.1 7777

Example without a port parameter:

Code:

samp.exe 127.0.0.1

It is important to know that the name is in the registry. (The reg key is SOFTWARE/SAMP).

Then it's a matter of visual work. Note; you'll probably want to validate that SOFTWARE/SAMP exists and has a valid SAMP installation path.
