Programmatically event in App Designer, is it possible?

I am trying to create an event programmatically in App Designer, like a "PushedButton" or a "ValueChanged". Is it possible? I know that I can call the callback function directly, without passing the "event" argument, but I wish I could use notify function.
notify(app.myButton, 'ButtonPushed')
% Error using matlab.ui.control.Button/notify
% Cannot notify listeners of event 'ButtonPushed' in class 'matlab.ui.control.Button'.

For push buttons, the event is a ButtonPushedData object with properties Source (button handle) and EventName ('ButtonPushed'). Your switch/case matches the Source with known button handles.
From what I understand, you want to directly call the ButtonsPushedCallback function and provide a known button handle so you can run some code that belongs to one of the cases. If that's correct, when you call ButtonsPushedCallback, if you have access to the app object, you can provide the button handle within a structure with a field named Source.
Example:
S = struct();
S.Source = app.Button1;
ButtonsPushedCallback(app, S)

Glad it worked out! You could simplify my answer to create the structure and the field within the same line:
S = struct('Source', app.Button1);
