if you just put the name of gui2 inside the callback of the pushbutton of gui1, then gui2 does not open?

gui1_mybutton_callback(hobject,evnts,handles)
gui2;

use setappdata to pass data for more complex interation then

Its difficult to provide sample code without a more specific question where you provide code of your own which I could adapt my example code to. I think we're at the stage of doing some initial background reading. Broadly, you need to work with the handle to gui2 (as launched from the callback above), and then be using get() & set(), & getappdata() & setappdata() to manipulate the object properties of both gui's and store any data directly to the root for sharing as appropriate.

e.g.

    setappdata(0,'my_variable',23) % set variable "my_variable" with value 23 to the root [i.e. 0 indicates the root]

Structures are handy in some cases:

    mystruct.myval = 23;
    setappdata(0,'mystruct',mystruct) ;
    clear mystruct
    mystruct = getappdata(0,'mystruct') ;

See the end of this section of the FAQ where it refers you to Doug's tutorials.

It's also not clear if you want one GUI to actually control another GUI, like change images, text, and plots on it, or if you just want to launch the second GUI, have the user interact with it, and then return values back to the first GUI. Which is it?
