How can I use GUI to choose parameters for another m file?

I am using an m-file filled with parameters to run a simulink model. However, I have many configurations that I want to easily chose without having to change them in the m-file. Therefore, I am trying to use a GUI to select the configuration (speed, test condition, and so on)and then have the GUI spit out my configuration to the mfile that will run the simulink file. I am having trouble getting information from the GUI to the mfile. Any help would be greatly appreciated. Thanks!
