Ngozika - if you are using GUIDE to create your GUI, then you could try the following (which assumes that your pushbutton, edit text, and static text controls are named (tagged) as pushbutton1, edit1, and text1 respectively)
 function pushbutton1_Callback(hObject, eventdata, handles)
 strToCheck = char(get(handles.edit1,'String'));
 if ~isempty(strfind(strToCheck,'a'))
     set(handles.text1,'String','good');
 else
     set(handles.text1,'String','not good');
 end
In the above, we use strfind to determine if the character 'a' is within the string that the user typed in.
