L-Est97 to WGS84 coordinates converter with GUI interface

HW1

Task

Locations on earth are often expressed in geographic degrees (latitude and longitude). But when you are surveying you need to talk in meters (or feet). This is because - depending on the application - you use a geographic or projected coordinate system.

A geographic coordinate system (GCS) is a coordinate system which uses a three-dimensional spherical surface (ellipsoid) to define locations on the earth. A common choice of coordinates is latitude and longitude. For example, main entrance of Taltech IT College is located on 59Ā°23'43.02" North and 24Ā°39'50.78" East in the WGS84 coordinate system.

In a projected coordinate system (PCS) you project the geographic coordinate that you have measured, to, for example, a cylinder which you roll out easily on two-dimensional surface (the map). There exist many different projections. For example, main entrance of Taltech IT College is located on X=6584335.6 and Y=537731.1 in the Estonian L-Est97 coordinate system. NB X-axe direction is to North and Y-axe direction is to East. https://xgis.maaamet.ee/xGIS/XGis?app_id=UU82&user_id=at&punkt=537731.1,6584335.6&zoom=95.2690129536204&LANG=2

Task: You need to wrote program which converts coordinates from WGS84 coordinates to L-Est97 and vice versa. Additional requirements: Python 2.7 and 3.x, documentation and testing are mandatory. GUI is recommended.
