Sincerely, I don't get quite get the point of your post. Was it Excel the reason why everything got slower or was it really GTK+ on Windows? Have you measured this?
OK. Of course, if you're showing a complex data grid, it might require time to show up. But what is it what requires time? Drawing the chart or processing the data? The former is just drawing stuff into the screen and if the library is well-designed, it shouldn't have any noticeable critical delay (gnome-system-monitor, e.g.). If the data is complex, then the issue is at the backend, I guess, and even a console ncurses-based UI would lag in that case. In that latter case, all you can do is to tell the user to wait, I think, but it'd be very rare that the issue was the chosen GUI toolkit. If it was, it should be reported as a bug.
