GUI – wxErlang

We are going to implement a Wxwidgets GUI that will allow us to run the application with few options:
Read data set from a csv file
Send the data “for learning mode” to the neural network.
Prediction
Showing the results with statistics
The gui will be a menu with different options.
As we don’t have deep knowledge in erlang, is there an easy way to achieve this e.g. start from a GUI template and change the functionality according to our needs? I found wxFormBuilder in Google and created the buttons, but where should I implement the onclick functions? How do I use the generated xrc in a wxErlang project? Any suggestions could help.
Thanks!
