Here's what people are saying about wxPython...
-- Eric S. Raymond
wxPython is the best and most mature cross-platform GUI toolkit, given a
number of constraints. The only reason wxPython isn't the standard
Python GUI toolkit is that Tkinter was there first.
-- Guido van Rossum
"Tkinter is dead, Java is dead, wxPython rules! That's all there is to say."
-- Robert Roebling
"I've written some rather involved applications with Python/Tkinter. wxPython beats it hands down... The widgets are better (being based on GTK for Linux) and the class setup is immediately useable. wxPython gives me a good reason to never even worry about using Java."
-- Aaron Rhodes
"The Python community needs to give up on Tcl and come join us. wxPython is wonderful stuff."
-- David Priest
"BTW, great work! I've definitively switched from Tk. I work on Win32, anybody who works on Win32 should switch!"
-- Michel Orengo
I have just picked myself up off the floor having looked at the wxHTML stuff in the new beta! wxPython is moving from excellent to completely awesome very quickly indeed.
-- Sean McGrath
Thanks for such fantastic work on wxPython. As a newcomer to
Python the power of this GUI library blows me away. I will never
use anything else.
-- Mark Evans
This toolkit has transformed the way I work.
-- Dr. Daniel B. Koch
