I saw your tkinter project on GitHub and thought you might like to see my Python GUI graphical curve fitter and surface fitter on github, BSD license. The matplotlib 3D surface plots of the fitted equations look really cool (my background is in nuclear engineering and industrial radiation physics).
The code uses a linear solver if the equation is linear, and a non-linear Levenberg-Marquardt solver from scipy if the equation is non-linear. It automatically uses scipy's genetic algorithm to produce initial parameter estimates for the non-linear solver.
