changed "think" to "guessing" and added "but cannot prove" for emphasis.

Blow-up $\mathbb C^2$ simultaneously at all points of $\mathbb Z \times \{0\}$.

Part a) is evident for the blown-up manifold $X$ since it contains one-dimensional compact submanifolds. As for part b), I am guessing (but cannot prove) that the huge first Chern class of the line bundle $\mathcal O_X(D)$ associated to the exceptional divisor $D$ prevents the existence of a finite number of holomorphic or even differentiable charts.
